Re: [SOGo] SOGo and Active Directory - [NGImap4ConnectionManager] IMAP4 login failed

Wed, 24 Oct 2012 14:13:46 -0700 

Hi all,
I was able to found and fix the problem with help from both dovecot and SOGo IRC channels :) 


The problem was caused because SOGo was sending as username 
"[email protected]" and IMAP was expectng "gooduser" alone.



I corrected SOGo behavior by defining the parameter 
"IMAPLoginFieldName" in my defaults , under "SOGoUserSources". I made 
the parameter to equal "sAMAccountName" , restarted both memcached and 
sogod services and now IMAP is happily authenticating users.


This means adding to my .GNUstepDefaults:


<key>SOGoUserSources</key>
<array>

(...)

  <key>IMAPLoginFieldName</key>
  <string>sAMAccountName</string
</array>




Regards,
Josep

Hello,

I'm setting up a SOGO test environment before I migrate our current
mail
system to a new one, hopefully with SOGo as it looks great.


I have SOGo authenticating with MS AD using LDAP, and it works fine. 
I

added the instructions to the wiki, as it was not 100% obvious:
http://wiki.sogo.nu/ActiveDirectory

I have Dovecot authenticating with MS AD using ntlm (
http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm  ). This works
because
I can login to IMAP with Thunderbird with Domain users .


So my user can login to SOGo fine. But once it's inside SOGo and I 
try

to access mail with SOGo, I get the error on the logs:

On the IMAP side, here are the debug logs:

Thunderbird all works fine:

Any idea? Any hint? I've read the documentation PDF, searched the 
wiki,

searched Google... but I don't seem to find the answer.

Thank you in advance,
Josep
