Does UM6 support secure LDAP authentication?

Currently Being Moderated

Hi experts,


I've a customer with a security concern. He wants to know if UM6 utilizes a secure and encrypted method to authenticate with AD. In his environment only encrypted LDAP authentication is enabled.


I guess the base question is, if UM6 uses

- simple BIND (which is unsecure and exposes the user's credentials)

- Kerberos (which is the preferred way for AD communications anyway)


If simple BIND is used, is or can SSL/TLS be used to encrypt the authentication session?


If not - what are the options? Local users?


New Info from customer:


If he uses the standard port # 389, authentication works but is insecure.

If he enters the secure port # 636 he gets "Unknown authentication server error"


I assume UM6 does not switch to secure communication automatically, if the secure port is used?


regards, Niels
