Hi folks,

This is not exactly accurate - SASL can be used with external LDAP
authentication. SASL with an external LDAP server requires that the LDAP
server be able to either perform the necessary SASL calculations in
tandem with CommuniGate Pro, or even easier, to simply return the PLAIN
text password to CommuniGate Pro, and allow CGatePro to perform the SASL

This is documented in the Guide in External Authentication:

This will allow SIP, XMPP, and Pronto to work using SASL authentication
methods with an external Directory.

CommuniGate has a newly written authLDAP-SASL Perl plugin to do this,
which just needs to be tested and the method documented somewhat. We
hope to do this within the next few days.
