yes, but i have no uppercase names. i should mention, that my imap server 
(cyrus) authenticates against the same ldap database as horde. before i 
switched horde auth to ldap, i queried the ldap over imp auth. that worked 
always, i never got an "login failed" error. but since i first make an horde 
ldap auth and then an login to cyrus, the cyrus login failes sometimes.

i use the following versions:
horde 3.1.5
imp 4.1.5
cyrus-imapd 2.2.13
cyrus-saslauthd 2.1.22

Neys.
