[horde] cannot login after update

[Matthias]

Hello,

I just updated everything via pear install horde/....

Since I update regularly I had to update only
Horde_Service_Facebook
Horde_Kolab_Storage
Horde_imp
Horde_nag
Horde_turba

Everything seemed to go fine. All Modules
showed being updated.
Then I clicked on Webmail
No folders showed.
Then I logged out of horde.
Since then I can no longer log in to horde!
"Wrong user or password" (in german) is the
message I get on the horde login screen.
The auth-log shows:

Could anybody please help me to be able to log in again?

What went wrong?

Thanx!
