[horde] IMP - Authentication problems

[Angel Parra]

Hello,

There is several authentication problem with IMP

Using Horde 6.0.0:

    - Horde (horde) 6.0.0
    - Mail (imp) 7.0.0


1. With horde Authentication as:

    $conf['auth']['driver'] = 'application';
    $conf['auth']['params']['app'] = 'imp';


If you have a imp "content" in the main horde input it is marked as:  
IMP is marked as authenticated, but no credentials can be found in the  
session.

The "Mail" menu is not showed on the top bar.


2. If you use IMAP authentication "Mail" is accessible.


3. Other errors already shown:


    - If you press on the download icon of an attached file: 500  
Internal Server Error
    - If you press on "Download all (2 attachments)": A fatal error  
has occurred User is not authenticated.

It seems all problems related to Authentication (and tokens).


Best regards

Angel
