What do you see in the FDS logs  (tail
/var/log/dirsrv/slapd-<instance-name>/access
Can you check the basic things

1. Is the DIrectory server running on port 636 (netstat -tlnp | grep 636)

2. If you do ldapsearch -x -ZZ -b "your basedn" are you able to search

3. Does getent passwd and getent group enumerate users on the client ?
