[Dovecot] LDAP against Novell eDirectory: 'Confidentialityrequired'

[Jim Moseby]

Martin.
 
Thanks for the reply.  
 
I tried your solution, didn't work for me.  
 
What happened was, I changed to use 'uris' instead of 'hosts', set 'tls=no', and restarted dovecot.  I got this looping over and over:
 
dovecot: 2010-05-20 12:03:20 Error: auth(default): LDAP: ldap_result() failed: Can't contact LDAP server
dovecot: 2010-05-20 12:03:20 Error: auth(default): io_loop_handle_remove: epoll_ctl(2, 8): Bad file descriptor
 
Every other time I have seen the message 'Confidentiality required' when querying LDAP (in my PHP module for instance), all I had to do was enable TLS, and the problem was solved.  Dovecot seems to be an exception.
 
Cheers!
 
Jim

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
