Vexing SSL LDAP issue

For a secure application we plan on using we require SSL
authentication to LDAP. I have a root CA installed as a
stand-alone CA, on a server called SERVER1. This does not
have AD on, and is a stand-alone Win2k3 server. I have
another server, Server2 which is a Domain Controller, has
CA installed as a sub-CA to Server1. During the sub-CA
install I pointed to the RootCA, and answered "Yes" to the
prompt about trusting the RootCA.

In troubleshooting why LDAP SSL is not working, when I
execute lpd on Server2 (the DC), it can connect to it's AD
(i.e LDAP) over the non-ssl port (389). However, when i
try to connect using the SSL port (636) I get an error.
(Simple Binf Failed: sername:636).

Any help on debugging this will be truly appreciated.

Thanks,
