LDAP + Active Directory Authentication Issue

[stefan.paetow at diamond.ac.uk]

Luke,

Unless you are storing passwords in Active Directory in plain text or you want to use Kerberos authentication, you will have to use MSCHAPv2 (or its EAP equivalent, EAP-MSCHAPv2).

In that case, follow http://confluence.diamond.ac.uk/display/PAAUTH/Using+Active+Directory+as+authentication+source and see if that's more useful than the URL you originally posted.

And please, post a full debug log of an authentication attempt. It's much appreciated by the gurus on the list. :-)

Stefan

Subject: LDAP + Active Directory Authentication Issue

Hi, I am trying to authenticate users against Active Directory using LDAP. I can perform the initial bind using an ldap bind account. I can then successfully find the Distinguished Name in Active Directory given a domain user's username. I would now like to re-bind using that Distinguished Name in order to authenticate the password they supplied as described in point 4 here:

http://thecarlhall.wordpress.com/2011/01/04/ldap-authentication-authorization-dissected-and-digested/

The problem I am having is my server errors out with 'No Auth-Type found' come authentication time. I added 'set_auth_type = yes' to mods-available/ldap but it seems to have had no effect.

I am very new to this so am still finding my feet - can anyone help?


Subset of output from terminal (redacted some personal info):
