[horde] Horde imp Webmail user Login Fails with Error [login failed]

[Pat Taylor]

IMP: H3 (4.1.4)
PHP Version: 5.1.6
Apache Version: 2.2.4
OS: FC6


I have had an issue going on for some time now regarding users NOT being able to
log onto Horde imp [webmail].

No matter the user, when one attempts to logon with correct credentials he/she
is directed straight back to the login screen.

When I run 'test.php'I receive no immediate errors.
After running 'PHP Mail Server Support Test' I see that a certificate error has
occurred, I am assuming that is my primary problem for login. I'm just unsure
how exactly to resolve the issue???
