Title: Having trouble with LDAP Authentication...

I’ve google and searched, and have had very
little luck...
I have:
- Installed all the packages.
- Configured and have running OpenLDAP.
- Migrated my passwd/shadow/group/hosts files
into the directory
- Tested the directory using ldapsearch
- Installed LAM (web interface to LDAP
authentication)
- Added a user using LAM.
- Confirmed user is in directory.
- Confirmed user is not in /etc/passwd
- Confirmed using “getent passwd | grep
username” that the user is listed.
- Confirmed using “getent passwd” shows two
records for each user except ldap-only users (one for
/etc/passwd, one for LDAP).
However,
“id username”
Returns unknown user
And trying to log in as username at either the terminal or ssh fails,
and upon examining the logs, the error message says unknown user.
I configured /etc/pam.d/system-auth using authcongfig-tui, adding only
the pam_mkhomedir.so line (and I tried it without that line as well).
Everything seems right – but its not working. Can anyone offer
any suggestions as to where I should be looking? If necessary, I’ll
post my /etc/openldap/slapd.conf, /etc/openldap/ldap.conf,
/etc/pam.d/system-auth, and /etc/nsswitch.conf files – I just didn’t
want to send them if not necessary.
Any help or suggestions would be appreciated. Thanks!

We'll assume you've properly configured your OpenLDAP server and can
query the directory and whatever user/group accounts you have created
are valid.
Now, you make no statements regarding the system that you are
attempting to authenticate from. Run 'authconfig-tui' from the
console/terminal and ensure the ldap server is specified.
See this page
(http://beginlinux.com/server_training/server-managment-topics/1316-set-up-ldap-client)
and concern yourself with the 2 screenshots for now. You can tweak the
manual settings to your hearts content but ONLY need to set the options
contained in the screenshots to at least get LDAP auth working.
Make sure you leave an '*' next to 'Local authentication is sufficient'
as well so the system continues to auth local accounts. Placing a '*'
next to 'Cache Information' will enable nscd.
