[imp] login problem

[Vikram]

Hi there

My Horde/IMP is almost completely configured, please see:
http://doublehelix.popgen.org/mail/horde/test.php

I can access http://doublehelix.popgen.org/mail/horde/imp/test.php and can
login successfully.

MySql database for horde has been created, the one for turba is also
created.

When I go to http://doublehelix.popgen.org/mail/horde/imp/login.php I get a
login screen and when I enter the same user and pass information that I used
above, it doens't work, I end up with a "page not found error".

I dont know what is wrong now.  Any help would be greatly appreciated.

Thanks
Vikram
