Setup: FC2 on a workstation will all updates. 2 servers running Winblows server 2003 will all updates. Problem: I can't for the life of me figure out why I can't authenticate. I see Kerberos authenticates successfully, but nss_ldap cannot connect to the LDAP server. I guess it can't query LDAP to see what my UID is and fails on the uid < 100 for pam_unix. I modified the PAM files, ldap.conf, and krb5.conf files. Here are some excerpts from some log files.
