GroupWise 2012 Client - Ldap Authentication

We are in the process of changing our GW 2012 clients over to Ldap Authentication instead of the native GW authentication.

I have read in documentation that there can be issues when Concurrent Connection limits have been set.

However, in our test environment, I don't find that the GW 2012 Client login counts against the Concurrent Connection limits when authenticating via Ldap SSL.

Does either the GW 2012 client or WebAccess take a concurrent connection when logging in via Ldap?

Thanks, David.
