Subject: SASL authentication with external LDAP - for SIP/XMPP/Pronto

Difficulties using SASL auth "challenge-response" mechanisms with an
external LDAP directory have often been discussed here, including but
not-limited to these discussion threads on the mailing list:

(If your have been unable to authenticate via SIP, XMPP, or Pronto and
you are using an external LDAP directory - this was likely the cause of
the problem.)

Recommended Approach:
Please note that one technique to achieve SASL auth with an external
LDAP Directory is now documented at the following page, and a new
authLDAP plugin which implements it is provided there:

Using this method, CommuniGate Pro can perform SASL authentication with
an external LDAP Directory - this allows for SIP, XMPP, and Pronto
(XIMSS) authentication (including Pronto SSL) via external LDAP.

(Please note: In order to use Pronto with SSL, CommuniGate Pro 5.1.12e
or later is required. For SIP and XMPP authentication, as well as Pronto
non-SSL SASL authentication, this technique should work with earlier 5.1

An example is provided there for OpenLDAP configuration.

Please review this and let us know if you have any questions.
