[sork] Troll problems

[Barry]

I have 2 servers running Horde with Troll installed.  Both servers are
running perfectly with horde and all of the other modules, both servers
are configured exactly the same with the exception of DN.  The first
server is SuSE 8.0 with php 4.1.0 and apache 1.3.23 and it gets memory
errors while trying to go to Troll.  I have already had that question
answered as to why it does that.  The second server is Debian 3.0 with
php-4.1.12 and apache-1.3.26.  When I try to enter Troll after having
already authenticated Horde redirects me back to the login screen and I
login again after which I get a HTTP 404 - File not found Internet
Explorer.  I have used the set_perms.sh on the horde directory and I
still get this error.  Does anyone have any clues as to why this
happens?
