Luke,

Can you send a debug log of what happens when you send it from your console server please (the full log, no redactions).

Stefan

Thank you all. With your help I have made progress.

I can now successfully authenticate the user 'test' against Active Directory if I open up another terminal and run:
radtest -t mschap test password localhost 0 testing 123

However, the 'no Auth-Type found' error still occurs if I send the request from my console server. Is this because the request from the console server needs to specify use of mschap?

Thanks again

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):
