RE: freeradius and ntlm_auth howto

["King, Michael" <MKing@bridgew.edu>]

Some things I've noticed from your attached files

 

Module: Loaded MS-CHAP
 mschap: use_mppe = yes
 mschap: require_encryption = yes
 mschap: require_strong = yes

 

I've never enabled these before, I'm unaware what affect they will have

 

 

tls: pem_file_type = yes
 tls: private_key_file = "/etc/raddb/certs/cert-srv.pem"
 tls: certificate_file = "/etc/raddb/certs/cert-srv.pem"
 tls: CA_file = "/etc/raddb/certs/demoCA/cacert.pem"
 tls: private_key_password = "whatever"
 tls: dh_file = "/etc/raddb/certs/dh"
 tls: random_file = "/etc/raddb/certs/random"

 

Did you generate your OWN certs...  They one's that ship with the server ARE NOT vailid. You have to generate your own.

 

rlm_eap: Loaded and initialized type peap
 mschapv2: with_ntdomain_hack = no
rlm_eap: Loaded and initialized type mschapv2

 

That doesn't look right

 

 

 

BUT YOUR FINAL ANSWER:

 

 

xec-Program: /usr/bin/ntlm_auth --request-nt-key --username=sstruyf --challenge=b9ee04ca891c7b7d --nt-response=79b960c773fa101929d3bf8e738168e8b6d8ae8cd61f64f0
Exec-Program output: Account locked out (0xc0000234)
Exec-Program-Wait: plaintext: Account locked out (0xc0000234)
Exec-Program: returned: 1
  rlm_mschap: External script failed.
  rlm_mschap: FAILED: MS-CHAP2-Response is incorrect

 

 

Your account in the domain is not correct.

 

Looks like it's been disabled or something.

 

Fix that first before you change anymore config files.

Michael,
I sent my reply already to the list, but due to the size(larger than 100k) it had to be reviewed by the admin and after a week it was rejected.
Below you can find the mail. Thanks for helping me.

I added the debuglog as attachment(as it is a little large to paste here).
This is the mschap config:
 mschap {
                authtype = MS-CHAP
                use_mppe = yes
                require_strong = yes
                with_ntdomain_hack = yes
                require_encryption = yes
                ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{mschap:User-Name} --challenge=%{mschap:Challenge} --nt-response=%{mschap:NT-Response}"
        }
