webmail and GSSAPI authentication to imapd

[ph.softnet@gmail.com]

PS: The other way around this (for everybody who's interested), is to
setup Cosign, wich makes apache setup the _SERVER['REMOTE_USER']
variable to the right username (after successfull authentication).
Then modify the Auto.php , authentication driver of horde, to set
$username and $password to $_SERVER['REMOTE_USER'].Then, make IMP to
perform transparent authentication (usign horde's authentication
credentials) and  contact a local cyrus proxyd (from MURDER) wich is
run with proxyd -N, so it allows plain logins, and ignores
passwords.Off course you should only run this locally!This proxyd in
turn, takes care of the following procedure, wich is essentially to
authenticate to a cyrus-imapd backend using gssapi and a special
account.
