If you delete or change the name of the container originally passed to namconfig, you need to delete nam.conf and rerun namconfig.
When Linux User Management is configured on a workstation, the base-name field is specified in the nam.conf file. If the container that the base-name field references is deleted from the server or its name changed, the following problems result:
Users enabled for Linux User Management are no longer able to access the assigned server.
When a Workstation object is reconfigured by using the YaST > Linux User Management module, an error results stating that the configuration module is unable to connect to LDAP because the server or the specified user does not have rights to configure Linux User Management.
Deleting nam.conf and rerunning namconfig should fix the problems.
