None of the LUN assignments of any of the volumes on the SAN have changed since mapping them to the ports connected to each individual server. So far my searches for a solution have turned up dead-ends and if anyone is able to help, I'd greatly appreciate it. Thanks, Trevor T.

[CentOS] OpenLDAP, PAM, GDM Configuration on CentOS 5.5
Hello: I am currently establishing a LDAP installation for my department and hope to get a little help on some of the finer details of the configuration. OpenLDAP 2.3.43-12 is currently installed, configured and running on one of my servers with a few client installations querying authentication information from it. The ppolicy schema has been added to the configuration and a password policy has been added to the directory under cn=default,ou=Policies,dc=domain,dc=com. Users are able to authenticate properly on the client machines to at least login; however, I have been unable to achieve the following functions: - Force user to change password on first login and display a prompt from gdm to facilitate the change - Lock user account from access and display a message from gdm to that fact These workstations are being used in a restricted mode so that the user may only work within X and may not open a terminal. Any help with this particular problem would be appreciated. Thanks. Trevor T.
