I'm getting this same error too.  Everything worked fine a couple days
ago, and now suddenly it's broken.  I can't find anything that changed; I'm
the only one with root access on the box and the only thing I've touched
recently has been something completely unrelated to Horde.

Digging a little, it looks like the error is coming from imp/redirect.php
being required from imp/lib/base.php, which according to the comments
should happen because we have valid login credentials but don't have an IMP
session, due to a single-signon/transparent auth setup (which I am using).
That would be fine, except that redirect.php requires lib/base.php, so if
base.php is in turn requiring redirect.php, we have a problem.

That's as far as I've gotten so far.  Any thoughts?
