[imp] ERR: HORDE IMP is marked as authenticated, but no credentials can be found in the session.

[Alex]

Hi Simon,

Thank you very much for your reply. I had already tried both links that you
provided. Unfortunately both do not help to solve my problem.

1. Link 1 just states "There currently seem to be some issues with sessions
and custom session ids via RPC under certain circumstances that are yet to
be found." It provides no solution. Also the problem is different:
ActiveSync works for me! Its just that I cannot access the webinterface for
IMP (Kronolith, nag, etc. still working!)

2. Link 2 refers to database connection on port 3306. I do not use port
3306 but instead unix sockets. The database connection works for all other
PHP applications (e.g. adminer) on the same host, so I do not suspect this
to be an issue.

I do not understand why you stated that "You're also not installing horde
in a manner recommended by the devs". Of course I followed the instructions
on

https://www.horde.org/apps/webmail/docs/INSTALL

which should be the recommended way, no?

Everything worked without any problems, before I did an apt upgrade on the
underlying OS. Since all other apps continue to work without problem, I
think the issue might be specific to Horde and I was just looking for tips
on how to debug and find a solution.

To your questions:
1. As per default, I use dovecot for authentication. Dovecot is recommended
by Horde.

2. Dovecot version 2.2.22, postfix version 3, PHP version 5.6.30

Thank you for your support
Alex
