Imp not authenticating thru Horde

[Harry Hoffman]

Hey All,
    I have moved my horde/imp/etc. install to a virtual server under
apache. Now when I log into the Horde framework I have to also login to
IMP to view mail. I have registry.php setup to use IMP authentication and
it worked just fine before this. Any pointers??

Thanks,
Harry
