anyone aware about this problem in LIferay 6.1 GA2.
trying to connect ldap using "ldaps" but fail.

It's working ok for me.

Simply got installed my certificates in my app server/jdk.

I connected Ldap with liferay in 6.1.
proecess used:
LDAP server- Apache DS
Jexplorer for ldap browser.
and configured it through control pannel and get connected fine.

are you providing correct information :
User DN- uid=admin,ou=system
Password- secret


from control panel after filling information when you use test connection.
Are you getting any log on back-end?

So guess you are hitting this issue:

http://issues.liferay.com/browse/LPS-30992

Have configured any time out error, in Liferay and/or your LDAP server?
