Re: OpenLDAP Proxy for Active Directory Authentication

[Jason Brandt <jbrandt@fsmail.bradley.edu>]

That appears to be exactly what I was looking for.  So, if I used something like: {SASL}user@domain in the userPassword attribute, it would use external auth, whereas if we populated the attribute with the SSHA password, it would still authenticate via LDAP, correct?

Appreciate the help.

You could use pass-trough authentification with SASL. See
