I had a similar issue. Had Debian 4 with Horde-Webmail 1.2.3 running.
Then moved the whole hosting thing (many customers) to a Debian 6. 
Horde didn't work. I upgraded this to webmail-1.2.10 - did not work.
In the horde logs (and mail.logs) I saw that the login was ok.

Then I used a new installation with horde-webmail-1.2.10, and set it 
up from scratch - using the values I had...

This did the trick.... - I don't know exactly why...

Hope this helps
