Sorry for the short topic :P, but I didn't really know how to figure this out.


  • Red Hat Enterprise Linux Server release 5.2 (Tikanga)
  • Zimbra installed (6 Beta 2 Release 1547)
  • Only one domain created and populated with users.

We have 3k workstations that already have configured just the username for authenticating with the IMAP server. In order to reduce impact through this huge migration process we plan not to change anything on Wk's.

So, the problem is that we cannot make zimbra authenticate just with the username even when there is just ONE domain in configuration. On the other hand, webmail does allow login with just a username (i believe that's because of virtual hosts configuration).

In addition, Thunderbird is showing a "The current command did not succeed. This mail responded: LSUB failed". I don't see anything on zimbra.log when i reproduce this error. I couldn't check if other Thunderbird versions are showing the same error yet.

Any help will be much appreciated.

Thanks in advance
