[imp] IMAP authentication with hordeauth=full

[GZsolt]

I try to set Horde 3.0.4 to authenticate via IMAP and Imp 4.0.3 via Horde.
If I set hordeauth to 'full' in the servers.php the left frame doesn't
show the menu.
I found some messages about the same problem, but I didn't find the solution.
I use chrooted Apache 1.3.33, mod-php 4.3.10.

Is there any suggestions?

Thanks

Zsolt
