It may be possible to accomplish this, but you have a bigger problem than that. Who is ultimately responsible for your network? They should be the one that should have the authority to fix this. If No One person is sresponsible for Network services then you will have many problems like this in the future. Alternatively, You have a few choices. 1. Do what you propose = Alot of work and research and it may not be a success 2. Combine the two LDAP servers into one server with two trees make sure to use the least expensive non-proprietary server. 3. Install two routers and break the departments out of the sharing the same network. This is only cost effective if it prevents problems like this in the future. It may break other services too. BTW shame on the other guy for not checking the services that were running first before installing the same one. How many resources did he waste of the organizations' time and money by not doing his homework. Job Cacka -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx]On Behalf Of Ryan Golhar Sent: Monday, January 30, 2006 1:45 PM To: 'General Red Hat Linux discussion list' Subject: OpenLDAP + User Authentication I have an LDAP server which I'm using to authenticate my users from. Recently, another dept here put their own LDAP server in place with a different set of users that may/may not be in my LDAP. What I'd like to do is have my machines attempt to authenticate a user from my LDAP, and if the user doesn't exist, have the LDAP refer to the other dept's LDAP server. Is this possible with LDAP? If so, can anyone point me to where I can read up on this? I found a little information on superior referrals, but no detailed information on how it works.
