UCSM Authentication - MS Active Directory and Secure Communication

[DemPackets]

I have configured LDAP authentication through Microsoft Active Directory for the UCSM system. It's been working well. I went to configure LDAPs for secure authentication with my LDAP servers today and I received the pop up message:

"Warning: Port 636 is generally used for secure connection using LDAPs method. USCM supports startTLS which uses regular LDAP port."

Does this imply that USCM is using startTLS to secure communication between USCM and my LDAP servers by default? Or is authentication traffic going through the default port 389 sent in clear text?

Port 636 is generally used for secure connection using LDAPs method. UCSM supports

startTLS method which uses regular LDAP port.

I understand.

Does this mean if I do no select SSL or attempt to change the port under the LDAP provider I have created, that communications between the USCM and my LDAP server use startTLS and are encrypted?
