I have just installed Courier IMAP 1.3.8.1 and I am having some problems getting
LDAP authentication to work.

The LDAP directory seems fine and successfuly authenticates FTP clients ( using
Proftpd )

I am only using the pop3d and I cannot see what is going wrong.

In /var/log/maillog I get the following:

Jun 5 16:27:34 test1 pop3d: Connection, ip=[::ffff:127.0.0.1] Jun 5 16:27:51 test1 pop3d: LOGIN FAILED, ip=[::ffff:127.0.0.1] Jun 5 16:27:55 test1 pop3d: Disconnected, ip=[::ffff:127.0.0.1]

I get a bit of a pause between entering the password and it rejecting the login.
( Exactly the same pause as when LDAP is not running. )

All the correct daemons are started ( authdaemond.ldap, openldap etc) and I can
successfully deliver mail to a test maildir using Exim.

Can anyone help by either telling me what is wrong or how to get some more
information out of courier as to why the authentication is failing.

Many Thanks

Peter Rendle
