I posted this issue in the NW6X forums, but it may be better here. I do
apologize for the double post. In any case here is my issue:

Upgraded NW65sp5(OES) Server to NW65sp6(OES) and now contextless login on
clients does not work. Mix Clients 4.91sp2 and 4.91sp3

Looks like all necessary services and modules are loaded on the server.

I am using SSL Contextless logins. All was well until upgrade. Ran PKIDIAG
on server to clean up some errors. Rebooted the server with no luck.
Re-exported the cert and no luck. Contextless using port 389 are the same,
do not work.

Doing an LDAP lookup is successful. Server LDAP Trace constantly reports:

New Cleartext connection 0x700c9540 from 127.0.0.1:1222, monitor = 0x13f,
index = 10
Connection 0x700c9540 attempted operation 0x1:0x60 without TLS, err = 13
Connection 0x700c9540 closed




When I try to login using the LDAP contextless login the server reports:

New TLS connection 0x700c9540 from 10.2.20.42:4413, monitor = 0x13f, index
= 12
