[horde] DIMP causes Redirection Errors as Initial Application

[jchurchey at mountdesales.net]

Hello everyone,

I'm using Horde Groupware Webmail Edition 1.2.3. I am trying to set  
DIMP as the default
application. I set permissions on the DIMP module to allow all of the  
authenticated users
to use it. It is working for some users sometimes while others receive  
intermittent
redirection errors.

Here is the redirection as it is contained in the access_log of apache:

72.210.68.164 - - [04/Aug/2009:16:42:42 +0000] "GET /dimp/index.php  
HTTP/1.1" 302 -
72.210.68.164 - - [04/Aug/2009:16:42:42 +0000] "GET
/imp/redirect.php?url=%2Fdimp%2Findex.php HTTP/1.1" 302

This has been brought up on the list before, but I was not sure if I  
could implement
these hacks on the recent code base or if they would even work now:

Does anybody have any suggestions about what I can do to make DIMP  
work as the default
application consistently?

I've been digging through code and trying different things most of the  
morning. If
somebody else has some insight on this problem, it would be greatly  
appreciated.
