Explanation and  fix:

---------------------------

I also experianced this problem;IE  looping back to login page.

The problem occured if the client first goes to the horde2 login page and then

the horde3 login page.

This was occuring because I put a link in the horde2 login screen to the new

version.

The problem was caused by conflicting session cookies from the two

versions; both with the same name.

I solved it by changing the session name from the default "Horde" to "Horde3"

I just removed and re-checked out all of horde, and this problem still exists.

The only odd thing is that my apache is on port 81.

Any suggestions?

Trying to add to this.... looks like when I attempt to access horde 
via IE I get the inital login  page

http://server/horde/imp/login.php



I login, then I get bounced to redirect.php and I am again presented 
w/ the login screen.  I try to login again, and it still fails.



Then, I attempted to access http://server/horde/imp, logged in, and 
all was ok.



I don't know if this will help, but...



These errors do not occur in firefox.

Can't reproduce, no information in here to actually go on.

Not sure if this is just my install or not, but I have tried on 
several IE versions, etc...

Using IMP for authentication, I cannot login w/ IE.  I just get the 
login screen back.

It works fine w/ Firefox.  Using latest HEAD.
