Configuring LDAP server in Outlook

[Paul]

Hello,

I am trying to set up an LDAP server in Outlook, but I keep getting a
"Can't contact LDAP directory (81)" error. Strangely, however, the
LDAP server works fine when I set it up seemingly the same way in
Thunderbird. I've specfified the same port settings and required SSL.

Outlook will just not connect. I've tried logging on or not logging on
(Thunderbird doesn't seem to have this option). I'm using the latest
versions of Outlook, Thunderbird, and XP Pro. Any ideas why one
program will work but Outlook won't?

Thanks,
Paul
