Here are the packages naming conventions:

	Sample configuration files
	All MMC related sample configuration files are available in the python-mmc-base package, in directory /usr/share/doc/python-mmc-base/contrib/. You will find there OpenLDAP, SAMBA and Postfix configuration files.

... because Mandriva RPM packages for the MDS and the MMC are available.

Packages for Mandriva 2008 and Mandriva Cooker are available on Mandriva official repository. You will find an official mirror using the Mandriva mirror finder module.

Then, you can register a package repository with this command:

        urpmi.addmedia Community_Main ftp://ftp.free.fr/mirrors/ftp.mandriva.com/MandrivaLinux/official/current/i586/media/main/backports/

The OpenLDAP configuration can be easily done using the openldap-mandriva-dit-package.

        # urpmi openldap-mandriva-dit
        ...
        # /usr/share/openldap/scripts/mandriva-dit-setup.sh
        Please enter your DNS domain name [localdomain]:
        mandriva.com

        Administrator account

        The administrator account for this directory is
        uid=LDAP Admin,ou=System Accounts,dc=mandriva,dc=com

        Please choose a password for this account:
        New password:[type password]
        Re-enter new password:[type password]
        
        
        Summary

        LDAP suffix:   dc=mandriva,dc=com
        Administrator: uid=LDAP Admin,ou=System Accounts,dc=mandriva,dc=com

        Confirm? (Y/n)
        Y
        config file testing succeeded
        Stopping ldap service
        Finished, starting ldap service
        Running /usr/bin/db_recover on /var/lib/ldap
        remove /var/lib/ldap/alock
        Starting slapd (ldap + ldaps): [  OK  ]
      

And you're done, the LDAP directory has been populated and the LDAP service has been started.

Some tweaks needs to be done to the LDAP configuration so that the LDAP service suits to the MDS.

First, copy the MDS LDAP schema to the LDAP schemas directory:

        # cd /usr/share/doc/python-mmc-base*/contrib/ldap/
        # cp dhcp.schema dnszone.schema mail.schema mmc.schema /etc/openldap/schema/
      

Then, add these lines to the file /etc/openldap/schema/local.schema:

include /etc/openldap/schema/mmc.schema
include /etc/openldap/schema/mail.schema
include /etc/openldap/schema/dnszone.schema
include /etc/openldap/schema/dhcp.schema
      

Then, to avoid LDAP schemas conflicts, comment or remove these lines at the beginning of the file /etc/openldap/slapd.conf:

#include /usr/share/openldap/schema/misc.schema
#include /usr/share/openldap/schema/kolab.schema
#include /usr/share/openldap/schema/dnszone.schema
#include /usr/share/openldap/schema/dhcp.schema
      

Last, comment or remove these lines at the end of the file /etc/openldap/mandriva-dit-access.conf:

#access to dn.one="ou=People,dc=mandriva,dc=com"
#        attrs=@inetLocalMailRecipient,mail
#        by group.exact="cn=MTA Admins,ou=System Groups,dc=mandriva,dc=com" write
#        by * read
      

To check that the LDAP service configuration is right, run slaptest:

        # slaptest
        config file testing succeeded
      

Now you can restart the LDAP service:

        # service ldap restart
        Checking config file /etc/openldap/slapd.conf: [  OK  ]
        Stopping slapd:                                [  OK  ]
        Starting slapd (ldap + ldaps):                 [  OK  ]
      

	OpenLDAP example configuration
	You will find an example of OpenLDAP configuration in the directory contrib/ldap/ of the mmc-agent tarball.

	Already existing directory
	If you already have an OpenLDAP directory, all you need to do is to include the mmc.schema file.

	Debian based distribution
	When installing the slapd package, debconf allows you to configure the root DN of your LDAP directory, set the LDAP manager password and populate the directory. So you only need to include the mmc.schema in slapd configuration and you are done.

Get the file mmc.schema from the mmc-agent tarball, and copy it to /etc/openldap/schema/ (or maybe /etc/ldap/schema/).

Include this schema in the OpenLDAP configuration, in /etc/ldap/slapd.conf (or maybe /etc/openldap/slapd.conf):

        include /etc/openldap/schema/mmc.schema
      

This schema must be included after the inetorgperson.schema file. On Mandriva, the kolab.schema file is conflicting with mmc.schema, so you need to comment the include directive for the Kolab schema, else OpenLDAP won't start.

In the OpenLDAP configuration file, we also define the LDAP DN suffix, the LDAP manager (rootdn) and its password (rootpw):

        suffix          "dc=mandriva,dc=com"
        rootdn          "cn=admin,dc=mandriva,dc=com"
        rootpw          {SSHA}gqNR92aL44vUg8aoQ9wcZYzvUxMqU6/8
      

The SSHA password is computed using the slappasswd command:

        # slappasswd -s secret
        {SSHA}gqNR92aL44vUg8aoQ9wcZYzvUxMqU6/8
      

Once the OpenLDAP server is configured, the base LDAP directory architecture must be created. Create a file called /tmp/ldap-init.ldif containing:

        dn: dc=mandriva,dc=com
        objectClass: top
        objectClass: dcObject
        objectClass: organization
        dc: mandriva
        o: mandriva
        
        dn: cn=admin,dc=mandriva,dc=com
        objectClass: simpleSecurityObject
        objectClass: organizationalRole
        cn: admin
        description: LDAP Administrator
        userPassword: gqNR92aL44vUg8aoQ9wcZYzvUxMqU6/8  
      

The userPassword field must be filled with the output of the slappasswd command. Now we inject the LDIF file into the directory:

        # /etc/init.d/ldap stop
        # slapadd -l /tmp/ldap-init.ldif
        # /etc/init.d/ldap start
      

	LDAP suffix
	In this example, the LDAP suffix is dc=mandriva,dc=com. Of course, you can choose another suffix.

	Changing the OpenLDAP manager password
	You can't change this password using the MMC interface. You must use this command line: ldappasswd -s NewPassword -D "cn=admin,dc=mandriva,dc=com" -w OldPassword -x cn=admin,dc=mandriva,dc=com

This section need to be updated.

Install FDS according to the FDS documentation.

The LDAP schemas we provide must be converted and then imported into FDS.

This part is written in Python, and use lots of third party tools.

In this table, we give the needed packages for each distribution and each MMC components.

If you have informations for other distributions, you're welcome :)

	CentOS DAG repository
	For some package, you will need to add the DAG repository to yum. Create a file named /etc/yum.repos.d/DAG.repo containing: # DAG Repository for RedHat Enterprise 4 / CentOS 4 [dag] name=DAG Repository baseurl = http://apt.sw.be/redhat/el$releasever/en/$basearch/dag gpgkey=http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt gpgcheck=1 enabled=0

Get the current mmc-agent tarball at this URL: ftp://mds.mandriva.org/pub/mds/sources/current/

        # tar xzf mmc-agent-x.y.z.tar.gz
        # cd mmc-agent-x.y.z
        # make install
      

The last command starts the installation: the MMC agent and all its plugins are byte-compiled and installed.

The default $PREFIX for installation is /usr/local. Here are how the files are installed:

When the MMC agent starts, it looks for all the installed plugins, and tries to activate them. Each plugin has a self-test function to check if it can be activated or not. For example, if the « base » plugin can't contact the LDAP, it won't be activated. It the SAMBA schema is not available in the LDAP, the « samba » plugin won't start.

The MMC agent always tries to enable the plugin « base » first. The MMC agent won't start if the plugin « base » can't be activated.

You can find a full description of the MMC agent configuration file there.

With the default configuration file we provide (/etc/mmc/agent/config.ini), the MMC agent listen locally to incoming XMLRPC over HTTPS connections on port 7080.

You can find a full description of the MMC base plugin configuration file there.

The main part of the configuration (/etc/mmc/plugins/base.ini) is to set the LDAP server to connect to, and the credentials to use to write into the LDAP.

The « defaultUserGroup » option must be set to an existing group in the LDAP. You will have to create it using the MMC web interface if this group does not exist.

You can find a full description of the MMC SAMBA plugin configuration file there.

You shouldn't need to edit the configuration file (/etc/mmc/plugins/samba.ini). This plugin won't be activated if your LDAP directory does not include the SAMBA schema, and well-known RIDs. See the section Section 6, “MDS SAMBA configuration”.

ACLs must be enabled on your filesystem. The SAMBA plugin needs them to set the ACLs when creating shares, and SAMBA will be able to map NTFS ACLs to the POSIX ACLs.

If you use XFS, ACLs are enabled by default. For ext3, you need to enable ACLs in /etc/fstab.

You can find a full description of the MMC mail plugin configuration file there.

This plugin won't be activated if your LDAP directory does not include a special mail schema. See the section Section 7, “MDS mail service configuration”.

You can find a full description of the MMC network plugin configuration file there.

This plugin won't be activated if your LDAP directory does not include special schemas. See the section Section 8, “MDS network plugin configuration for integrated DNS/DHCP”.

To start and stop the MMC agent, use the /etc/init.d/mmc-agent script:

        # /etc/init.d/mmc-agent stop
        # /etc/init.d/mmc-agent start
      

The MMC agent must be started to use the MMC web interface.

When the MMC agent is started, all startup log messages are written to stderr and /var/log/mmc/mmc-agent.log.

Here is what is written (for example) if there is no error:

        # /etc/init.d/mmc-agent start
        Starting Mandriva Management Console XML-RPC Agent: mmc-agent starting...
        Plugin base loaded, API version: 4:0:0 build(82)
        Plugin mail loaded, API version: 3:0:1 build(78)
        Plugin samba loaded, API version: 3:0:2 build(78)
        Plugin proxy loaded, API version: 1:0:0 build(78)
        Daemon PID 13943
        done.
      

If there is an error:

        # /etc/init.d/mmc-agent start
        Starting Mandriva Management Console XML-RPC Agent: mmc-agent starting...
        Can't bind to LDAP: invalid credentials.
        Plugin base not loaded.
        MMC agent can't run without the base plugin. Exiting.
        failed.
      

The base plugin can't bind to LDAP, because the credentials we used to connect to the LDAP server are wrong. As the base plugin must be activated to use the MMC agent, the MMC agent exits.

        # /etc/init.d/mmc-agent start
        Starting Mandriva Management Console XML-RPC Agent: mmc-agent starting...
        Plugin base loaded, API version: 4:0:0 build(82)
        Plugin mail loaded, API version: 3:0:1 build(78)
        Samba schema are not included in LDAP directory
        Plugin samba not loaded.
        Plugin proxy loaded, API version: 1:0:0 build(78)
        Daemon PID 14010
        done.   
      

In this example, the SAMBA schema has not been detected in the LDAP directory, so the SAMBA plugin is not started. But this plugin is not mandatory, so the MMC agent doesn't exit.

In the .ini file corresponding to the plugin, set « disable = 1 » in the main section.

The MMC web interface is written in PHP4. Basically, you just need to install an Apache2 server with PHP4 (or PHP5) support.

The XML-RPC module of PHP is needed too.

The mmc-web-base package contains:

The others MMC web modules available are:

All this module depends on the mmc-web-base module. They won't work if the mmc-web-base module is not installed.

A MMC web modules won't show in the web interface if the corresponding Python plugin is not loaded by the contacted MMC agent.

For example, you installed the SAMBA web module, but the SAMBA Python plugin of the MMC agent the web interface is connected to has not been activated. This will be detected and automatically the SAMBA management module of the web interface won't be displayed.

Get the current mmc-web-base tarball there.

        # tar xvzpf mmc-web-base-x.y.z.tar.gz
        # cd mmc-web-base-x.y.z
        # make install HTTPDUSER=apache
      

For some distribution (e.g. Debian based distro), you must use HTTPDUSER=www-data.

The installation process copies files to:

You can find a full documentation of the mmc.ini file there.

What you need to change in this file is:

To connect to the MMC web interface using an URL like http://IP/mmc, we add an alias to Apache2:

        # cp confs/apache/mmc.conf /etc/httpd/conf.d/mmc.conf
      

Then don't forget to reload the Apache service.

Now you should be able to see the MMC login screen at this URL: http://IP/mmc

You can always login to the MMC web interface using the login « root » with the LDAP administrator password.

After you installed the MMC, this is the only user you can use to log in, because the LDAP directory entry is empty.

The MMC web tarballs are available there.

They are all easy to install. For example:

        # tar xvzpf mmc-web-samba-x.y.z.tar.gz
        # cd mmc-web-samba-x.y.z
        # make install
      

There are no configuration files for all the additional modules.

The MMC web interface communicate with the MMC agent using the TCP port 7080 (default configuration). Please check that your firewall configuration doesn't block this port.

The MMC web interface opens a socket to communicate with the MMC agent using XML-RPC.

On SE Linux enabled systems (e.g. Fedora Core 6), by default Apache can't open socket per policy.

So you need to fix or disable your SE linux configuration to make it works.

You need to import the SAMBA schema into the LDAP directory. The schema file is provided into the MMC agent tarball: contrib/ldap/samba.schema. But you can also use the schema provided by the SAMBA project.

Stop samba before modifying its configuration:

        # /etc/init.d/samba stop
        Or according to your distribution:
        # /etc/init.d/smb stop
      

In /etc/samba/smb.conf, you need to modify the « workgroup », « ldap admin dn » and « ldap suffix » to suit your configuration.

SAMBA also needs the credentials of the LDAP manager to write into the LDAP:

        # smbpasswd -w secret
        Setting stored password for "cn=admin,dc=mandriva,dc=com" in secrets.tdb        
      

Now, SAMBA needs to create the SID for your workgroup:

        # net getlocalsid MANDRIVA
        SID for domain MANDRIVA is: S-1-5-21-128599351-419866736-2079179792     
      

Use slapcat to check that the SID has really been recorded into the LDAP. You should find an entry like this:

        # slapcat | grep sambaDomainName
        dn: sambaDomainName=MANDRIVA,dc=mandriva,dc=com 
        ...
      

Now you can start SAMBA:

        # /etc/init.d/samba start
      

The LDAP directory needs to be populated so that SAMBA can use it. We use the smbldap-populate command from smbldap-tools.

This command populates the LDAP with the OUs (Organizational Unit), users and groups needed by SAMBA.

A RPM package of smbldap-tools is available there.

Now the smbldap-tools conf file need to be edited. Put this in /etc/opt/IDEALX/smbldap-tools/smbldap_bind.conf:

        slaveDN="cn=admin,dc=mandriva,dc=com"
        slavePw="secret"
        masterDN="cn=admin,dc=mandriva,dc=com"
        masterPw="secret"
      

smbldap_bind.conf defines how to connect to and write to the LDAP server.

Then edit smbldap.conf and set those fields:

        SID="S-1-5-21-128599351-419866736-2079179792"
        sambaDomain="MANDRIVA"
        ldapTLS="0"
        suffix="dc=mandriva,dc=com
        sambaUnixIdPooldn="sambaDomainName=MANDRIVA,${suffix}"
        #defaultMaxPasswordAge="45"
        userSmbHome=""
        userProfile=""
        userHomeDrive=""
      

Now the directory can be populated. Type:

        # /opt/IDEALX/sbin/smbldap-populate -m 512 -a administrator
      

A user called « administrator » will be created, and a prompt will ask you to give its password. Thanks to the « -m 512 » option, this user will belong to the « Domain Admins » group.

SAMBA needs that the OS use the LDAP directory to get user and group lists.

To do this, /etc/nsswitch.conf and /etc/ldap.conf (/etc/libnss-ldap.conf for Debian based distros) should be configured.

Your /etc/nsswitch.conf should look like this:

        passwd:     files ldap
        shadow:     files ldap
        group:      files ldap
        
        hosts:      files dns
        
        bootparams: files
        ethers:     files
        netmasks:   files
        networks:   files
        protocols:  files
        rpc:        files
        services:   files
        netgroup:   files
        publickey:  files
        automount:  files
        aliases:    files
      

Your /etc/ldap.conf:

        host 127.0.0.1
        base dc=mandriva,dc=com
      

By default, you want your new user to belong to the « Domain Users » group.

You just need to set the « defaultUserGroup » option to « Domain Users » in /etc/mmc/plugins/base.ini.

By default, the maximum password age of a SAMBA user is 42 days. Then the user will need to change his/her password.

If you don't want password to expire, type:

        # pdbedit -P "maximum password age" -C 0
      

If you want to check your current password expiration policy:

        # pdbedit -P "maximum password age"
      

If « enable privileges = yes » is set on your smb.conf, you can give privileges to SAMBA users and groups.

For example, to give to "Domain Admins" users the right to join a machine to the domain:

        # net -U administrator rpc rights grant 'DOMAIN\Domain Admins' SeMachineAccountPrivilege
        Password:
        Successfully granted rights.
      

Notice that you must replace « DOMAIN » by your SAMBA domain name in the command line.

	Users that can give privileges
	Only users that belong to the "Domain Admins" group can use the net rpc rights grant command to assign privileges.

The default SE Linux configuration may not allow SAMBA to launch the script defined in "add machine script", and so you won't be able to join a machine to the SAMBA domain.

You need to import our mail schema into the LDAP directory. The schema file is provided into the MMC agent tarball: contrib/ldap/mail.schema.

Once this schema is imported, you will be able to manage mail delivery attributes thanks to the MMC.

Example Postfix configuration files are included into the MMC agent tarball: contrib/postfix/.

We provide two kinds of configuration:

NSS LDAP configuration is needed to deliver mails with the right UIDs/GIDs.

See Section 6.4, “NSS LDAP configuration”.

This plugin allows to store in a LDAP directory:

The MMC web interface allows to easily manage the DNS and DHCP services.

The network plugin relies on patched version of ISC DHCP 3 and ISC BIND 9:

We provide Debian (Sarge/Etch) packages for LDAP patched versions of BIND and DHCP.

Configure your APT repository as in Section 2.3, “Debian packages”, and type:

        # apt-get update
        # apt-get install dhcp3-server
        # apt-get install dhcp3-server-ldap
        # apt-get install bind9
      

When managing the DNS zones, the MMC agent will create files into the BIND configuration directory (located in /etc/bind/). These files must be included in the main BIND configuration file so that the corresponding zones are loaded from the LDAP directory.

All the DNS zones are defined in the file named.conf.ldap. This file must be included in the main BIND configuration file named.conf. Adding this line at the end of BIND named.conf should be sufficient:

        include "/etc/bind/named.conf.ldap";
      

An example of named.conf filename for Debian based system is available in the directory contrib/bind/ of the mmc-agent tarball.

	BIND and OpenLDAP services startup order
	On most distributions, BIND is started before OpenLDAP during the boot sequence. If BIND/LDAP is used, BIND won't be able to connect to the LDAP directory, and won't start. So you may need to tweak your system boot scripts to fix this. The following command line should work on Debian based systems: # update-rc.d -f slapd remove && update-rc.d slapd start 14 2 3 4 5 . stop 86 0 1 6 .

The DHCP server needs to know how to load its configuration from LDAP. Here is a typical /etc/dhcp3/dhcpd.conf:

        ldap-server "localhost";
        ldap-port 389;
        ldap-username "cn=admin, dc=mandriva, dc=com";
        ldap-password "secret";
        ldap-base-dn "dc=mandriva, dc=com";
        ldap-method dynamic;
        ldap-debug-file "/var/log/dhcp-ldap-startup.log";
      

An example of dhcpd.conf filename is available in the directory contrib/dhcpd/ of the mmc-agent tarball.

Two new LDAP schemas must be imported into your LDAP directory: dnszone.schema and dhcp.schema.

Both are available in the directory contrib/ldap of the mmc-agent tarball.

To speed up LDAP search, you can index these attributes: zoneName, relativeDomainName, dhcpHWAddress, dhcpClassData.

For OpenLDAP slapd.conf configuration file, you will add:

        index zoneName,relativeDomainName eq 
        index dhcpHWAddress,dhcpClassData eq
      

For the DHCP service only, the MMC network plugin needs to create into the LDAP directory two objects:

The first start of the MMC network plugin should look like:

        ...
        Created OU ou=DHCP,dc=mandriva,dc=com
        Created DHCP config object
        The server 'your_server_hostname' has been set as the primary DHCP server
        Plugin network loaded ...
        ...
