LDAPS auth for WLC

[sam.lee]

I have a WLC 2504 currently authenticating via RADIUS to our Active Directory Servers.  I would like to transition to LDAPS authentication.  I know LDAP works, but would I be able to do LDAPS authentication.  I can't seem to find any pertinent documentation.

Like I said, there's a lot of documentation about LDAP authentication, and this doc shows LDAP authentication but only using clear text passwords.  I'm looking for LDAPS (LDAP over SSL) which sends encrypted passwords.  I can't find any documentation on that.
