How to use the support for urpmi configuration in ldap.
Contents |
[edit] Motivation
In order to ease the management of a group of computers running Mandriva Linux, urpmi can fetch it's configuration from a central ldap server. This allows with some scripts ( not yet written ) to either use an auto update system, or to allow to upgrade computers based on the name or anything else.
[edit] Discussion and development
The code can be found in mandriva svn, at http://svn.mandriva.com/cgi-bin/viewvc.cgi/soft/rpm/urpmi/trunk/urpm/ldap.pm?view=markup
Primary list for discussing is cooker-server.
Seek "urpmi ldap" on the archives ( there is some problems for the moment, either on gmane and archives.mandrivalinux.com )
[edit] Configuration of the client
First, in order to use it, you need to use a version 10.2 or newer. The urpmi-ldap package can only be found on cooker for the moment, but you can take the file ldap.pm from svn and place it in /usr/lib/perl5/vendor_perl/5.8.6/urpm/ldap.pm
If you can, install the urpmi-ldap package.
The configuration file is the same as pam_ldap, everything is in /etc/ldap.conf. urpmi will use the regular option, but you can prefix the option with urpmi_ if you need something different. The current options are 'base', 'uri', 'filter', 'host', 'ssl', 'port', 'binddn', 'passwd', 'scope'. They have the same meaning as pam_ldap.
By defaut, urpmi will fetch entries that match "(objectClass=urpmiRepository)", with an anonymous bind, and a sub scope.
Urpmi will cache the result in /var/cache/urpmi/ldap, in order to cope with a possible network failure. Automated cleaning of the source is planned, and therefore, this will allows to use this on a disconnected laptop.
[edit] Configuration of the server
The current schema can be found in cvs. Please note that everything is still a bit experimental, as the oid show.
[edit] Future development
- Support for round robin and multiple servers
- Support for srv record
- Support for dynamic configuration ( with variable expansion )
- A gui or a web interface to generate ldif
- Provides other scripts ( one to clean /var/lib/urpmi, one to install all rpms from a hdlist, something for auto installation )
