StartTLS with Crowd

[MEDITECH ADMIN TEAM]

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:
