[imp] IMP - Horde Login Problem

[sc2 at gmx.at]

here again the new mail...before i attached a file (30 kb) but it send to
moderator...(what i understand).

I installed horde, and imp
i set up registry, for auth over imp, pop3 server

here are the problem and my env.
/home/htdocs/horde  > Horde
/home/htdocs/horde/imp > Imp
i setup horde without SSL Auth.
i use sub.domain.com:99/ (99 a testing port - for our intern use)

now to my problems
-----------------------
when i use horde with auth over horde then i see the login screen, when i
use it over imp, then not
when i use manuall sub.domain.com:port/imp/login.php > then i see the login
screen ...
when i try to login over /imp/login, then it redirects to a fault site but
it seems that he does not check any POP3 server or so cause its coming very
fast the error page..(DNS or Server cannot be found)
no 404, or 505 error...ind error log i cannot find anythink.
the problem is i cant see which url he is using after pressing the login
button....
the same problem is when i use the "logout" button, but the used logut URL
is correct.

thx for help
