I looked into it and it seems that someone has already requested this feature in 2011: https://issues.apache.org/jira/browse/DIRSTUDIO-743
Is there any interest in enhancing the API to support client certificate authentication? It seems like the server project will eventually implement it. I'd wager that there are many others like me out there who use the directory API to connect to a non-Apache Directory LDAP servers - not by choice, mind you :-) Thanks for the quick response, Mike M
