Exception while synching groups with AD

[#1]

Ranger usersych is throwing an exception while connecting to AD: below is the exception, any ideas? I have verified that I can bind successfully with AD.

Are you using ldap://<ip/hostname>:636 or ldaps://<ip/hostname>:636 in the usersync configuration?

javax.naming.ServiceUnavailableException: xx.xxx.xx..xx:636; socket closed

Is LDAPS in place? If yes then make sure you are using ldaps in url

[#4]

@Neeraj Yes, I figure that much out and now its complaining about not finding the cert which I have imported into a truststore and pointing to it.
