I’m sorry that I was not more clear. Nsslapd seems to only be listening on ipv6 so the admin server never starts. After rebooting the server I ran service dirsrv start.  Running service dirsrv-admin start resulted in Starting dirsrv-admin: appearing on the screen with no ‘OK’ for at least an hour, after which I cancelled the command with ^z. Subsequent investigations led me to believe that the cause was nsslapd only listening on ipv6.

Ok.  I think you are running into https://bugzilla.redhat.com/show_bug.cgi?id=588480
Could you provide your /etc/hosts and/or getent hosts and/or DNS information for your hostname?

OK, I think I have all of these answered.

 

Can you post the error log from /var/log/dirsrv/admin-serv/error?

Running ‘grep nsslapd-listenhost /etc/dirsrv/slapd-INSTANCENAME/dse.ldif’ (with no quotes of course) does not return anything.

I don't see any errors - looks like the admin server is starting up?  If you do a service dirsrv-admin start or restart (while the directory server is running) do you get an error?  Does ps -ef|grep httpd show 3 processes?

I think that the problem is because slapd is not listening on IPv4.

grep nsslapd-listenhost /etc/dirsrv/slapd-INSTANCENAME/dse.ldif

Is there an easy way to fix this? Since it is a test server I _could_ wipe it and start over, but I don’t want this to be a problem when we move to production.

 

Thanks!
