If the hostname you use in ldap://<hostname> matches the CN -- you are good. 

If not, and subjectAltName is present, then <hostname> should be compared to 
values in subjectAltName. 

This is my understanding and as far as I can tell, it works in practice. If 
someone knows there is another way this works, hopefully they will jump in.
