Re: Raw backtrace multiple passwords not allowed
You sure you're not returning multiple password attributes from LDAP? Aki pass_attrs = 'mail=user, userPlaintextPassword=password_noscheme, =proxy=y, =pass=%{ldap:userPlaintextPassword}, =host=%{ldap:mailstoreHost}' I am returning the same password attribute into different fields : password_noscheme - to auth the user pass = to send plaintext password to backend This is the only workable solution I could muster to terminate encrypted passwords on the proxy layer.

Re: Raw backtrace multiple passwords not allowed
This turned into quite a large problem for me but think I have resolved it. After toying this a few settings I ended up (out of sheer desperation) setting "blocking = yes" in my LDAP configuration. Is this a logical thing to do? I couldn't find much on it other than i'm guessing queries are no long async. I don't really see the downside given the upside is auth is not crashing and causing password prompts for all my customers...
