ossim_acl.php

i have been working on getting OSSIM to work on a Debian (sarge)
machine. i had it pretty much set up, except that ACID wasn't
recognizing my sensor so i tried rebuilding the snort database. after
doing that, i can't get to any of the ACID or OSSIM config pages.
instead, it keeps forcing me to run ossim_acl.php, and even after
running that script, i cannot get to any of those pages. how can i
fix this?
