The odd thing ("no easy answers TM") is, that despite of the errors in 
log, the Samba domain WORKS for a little while. Machines and users log 
on, as if nothing happened. Users get authenticated, network shares are 
connected. After several tens of seconds (minute or so) smbd dies and 
domain dies with it.

The second odd thing is, that the very LDAP works well too. We can 
authenticate against LDAP server from SMTP, IMAP and eGroupWare, and 
local machine user's logon using PAM-LDAP. Just when we run Samba on the 
server to allow Windows domain logons, the Samba acts as described above..

We'll try to remove the quotes, however it works with them in Sarge well.

Please, specify, what kind of info do You need here. I don't understand 

Tomorow, we will try to remove the TLS, since the LDAP and Samba domain 
are running on the same machine. As TLS encrypts just the communication 
between them (hopefully, AFAIK???), it seems it is not needed there 
(???). This is just a workaround however, and not everybody can afford it.
