StartTLS with Crowd

I'm looking for basic instructions to use StartTLS with Crowd directory and an active directory server currently using ldap.  I've enabled StartTLS in the admin area and even though I am able to sync and pull users I get a ton of tls errors in the logs and some users are not getting authenticated.   All is good if I don't use TLS. Do I need to install a cert on the Crowd server for it to use StartTLS?  We don't want to control users in AD from Crowd, just a one way pull.

If we run this command from the Crowd Linux Console:
sudo openssl s_client -connect ADserver.com:636

We do get a valid certificate from the AD server.

Here are some documents I've found but I'm not exactly sure what is needed in our case.

Just an update,  I was able to add our wildcard cert which has allowed ldaps to work.  

If I run java SSLPoke adserver.com 3269 it works connects. but if I change it to port 389 for tls it doesn't work:
