[imp] logon failure... anyone? anyone??

[Geoff Sweet]

I am still baffled by this error.  When I attempt to login via the
horde/imp/login.php the browser returns this error:

": could not be found. Please check the name and try again."

However using the horde/imp/test.php authenticates just fine.

I have grepped recursively through the entire horde directory and no
file contains the error above.  So it must be some server response or
something.  I get the same error on all the browsers and OS's I have
tried from a client side.

I really want to get this working, so if anyone has any ideas please let
me know.
