Hi Marco,

try to check if LDAP REFERRALS are enabled.

I had a similar issue some time ago when trying to authenticate against an AD, which didn't worked (long timeouts) as long as I switched off REFERRALS in the systems ldap.conf. (more info you might get by 'man ldap.conf')

Cheers, Chris

I hope that someone will be so kind to help me into solving this really strange thing (don't know if it is a bug or not)

I have a samba4 server and want to use postfix+dovecot - dovecot version is 2.0.11

as for the postfix side everything is OK (all the LDAP lookups works without any error, tested also manually with postmap -q) the real pain is with dovecot deliver:

it seems that sometimes lda tries to lookup to the LDPA (samba 4) server, got a reply, an then report(after 2 minutes) a lookup timeout error

the really strange thing is that (very seldom) lda works, but most of the times I got the timeout error.

The strange thing is that if I use ldapsearch I never got timeout neither late replies, and even postfix performs its lookups without any issue it seems something related to lda itself (I do not know if I have a wrong configuration, but I think this is not a configuration issue, otherwise it should not work at all)

here are the information logged when it does not work - after this log you will find the one when I got the failure (if needed I can provide a .pcap file too)

(trailing and leading spaces of AT charcater has been added by me)
