ArcGIS for Server 10.1 failed to connect to Window Domain/LDAP as user store

We installed the server on Windows 2008 R2 with a domain user. Installation went ok, but when we tried to use either Window Domain or LDAP as user/role store, errors occurred:

Test connection failed.
[LDAP: error code 8 - 00002028: LdapErr: DSID-0C0901FC, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, v1db1]

We tried to use another tool to connect to our LDAP:636 and it was ok.
My questions is what the ArcGIS Server host settings and the domain server settings should be set for the two to communicate?

We haven't found any detailed about that.

Thanks in advance,
