Re: Connections timing out to OpenLDAP server

Could you tell us which smtp/pop server  are you using?

I suggest first on the machine where the mail server is running to :

ping the openldap server
check that the port 389 ( if it's the one used ) is opened when you nmap the ldap server from the mail server
then from, this start,
on the openldap server, you do a tail -f /var/log/syslog
on the mail server, try to do a connection.
If no logs appear in the syslog of the openldap server, then problably, the mail server is not able to contact the openldap server :

so this is probably an error in your mail config file

If there are any logs appearing in the syslog, this mean that there is a dialog between the mail server and the openldap server

in this case, this is probably because the mail server doesn't have the rights to access the ldap server.

As you say, the logs do not show any errors, but do they show at least any messages? Could you past them?

Well, the first thing I suggest is to try to duplicate the
problem using OpenLDAP command line tools (on the system(s)
which these other clients are running on).   If you're
unable to, that would suggest the problem is with these
particular clients, not the OpenLDAP server (or network).

I'm using OpenLDAP 2.2.26 on Debian to authenticate SMTP and POP/IMAP

The logs on the directory server do not show any errors from slapd.

Any clues on where I should begin troubleshooting?  These devices are
on the same switch and there are no other indications of connectivity
problems, so I think network issues can be eliminated.
