[horde] avoid authentication in Chora

[Philip Iezzi]

I did already ask this some time ago on that list but still didn't figure it
out in the meantime. If this is just a small configuration problem, please
point me into the right direction, I would really appreciate.

I'd like to run Chora without authenticating through Horde. There shouldn't
be any login required to use Chora. Just as you run Chora on cvs.horde.org
and like everbody else runs it. (and I did manage it in Horde 2.2.4, Chora
1.2 - actually also in a pretty "unclean" way...)
I'm running a current HEAD from CVS and set up Chora outside of the Horde
directory by changing path information in registry.php. Authentication is
done by IMP:
$conf['auth']['driver'] = 'application';
$conf['auth']['params']['app'] = 'imp';

Chora always redirects me to the standard Horde/IMP login.
As workaround I tried to just comment out the
Horde::authenticationFailureRedirect(); lines in /chora/lib/base.php, but
this seems to be a bad hack and produces other errors.

thx
