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 ?

Regards
Niranjan

where the server matrix is FDS  what I did was from FDS  "ssh matrix.trues.co.uk -l test1"  where test1 users exists in ldap dir

Dharmin



Hi,

Can you check What happens if you specify

ssl start_tls

instead of "ssl on"

Regards
Niranjan
