LDAP Contextless Login: User not found after searching the trees on the
following LDAP server(s):

I'm getting this error and can't get the LDAP contextless logins to
work. This is Client 4.91 SP1 so this issue should have been fixed back
in 4.9 SP2. I don't know what else to try. I checked with a counterpart
and his is setup like mine but his is working. Suggestions? Thanks.
