[Dovecot] LDAP against Novell eDirectory: 'Confidentiality required'

[Martin Ott]

Hi Jim,

I don't know why your setup is not working. I only can provide you some hints
from our working setup. We authenticate our users against a MS Active
Directory Server.

the uri in dovecot-ldap.conf is:
uris = ldaps://hostname

we  also had to add in /etc/ldap/ldap.conf

TLS_CACERT /etc/ssl/certs/certfile.crt
TLS_REQCERT demand

hope this helps,
Martin
