Authenticating clients against organization’s ldap

Hi, I'm quite new with ldap so not sure if the right wordings are used here. This is my situation: -Library environment with a system that contains library card users (unique barcode and pin # per user) -Setting up public Mac Leopard iMacs and need to allow users to use their library barcode and pin # to authenticate. -LDAP server is up and running for other services and authenticating against for other services. -Want to use this LDAP on the clients so that users can authenticate against. -LDAP on a separate subnet in the organization -Firewall in our organization has been configured to allow our subnet to communicate with LDAP. This is the current setup: -Clients running OSX10.5.6, patched and running ok. -Clients also have an OD configured so that our "staff" users can login. -OD service running on the Mac Server for our "staff" users. This is running fine when a staff wants to login. This is what I have done so far: -Added the LDAP server on a client through Directory Utility. -Put in the proper settings and now I have 2 directory servers listed with GREEN light and saying server is responding normally. -Tested look up of users from client... - In terminal I used the id command: "id " - I successfully get the user info for the user on the OD server with no problems - I then check a user that is suppose to be on the LDAP: "id " - Response I get is "no such user" Questoins: -What now? I have setup the directory utility to use settings from server -Plugged in the proper base search info -Everything on a static IP network (don't think this matters though). Any feedback would be great. Thanks in advance. -Garry
