I need to set up authentication and authorization for a RHEL5.4 system of servers using Red Hat Directory Server 8.1. I have something of a clue of how to set it up, but don't have a clue as to how to set up authorization based on either groups or roles. I have the users, roles, servers enumerated, but don't know 1/ how to configure this, 2/ how to force the LDAP run time check on the client. I've searched but haven't seen really any useful documentation. I'm looking for pointers to good documentation, instructions, etc. Thanks in advance.
