hmm - actuall my log output clearly shows the hook is being called
each time I log in so this is (for whatever reason) not the problem in
our case.

the real issue is no username is passed - I did look at the comments
in the hook templates, they mention this is the case when the user is
not authenticated. however, login and therefore authentication works
fine using ldap - I am wondering if we might have our whole auth chain
upside down (i.e. we should have imp authenticate against ldap/imap
while the rest of horde uses the imp for authentication instead of the
other way round) ?
