ntlm_auth with ms-chap

[Jürgen Obermeyer]

>   Well, radclient implements MS-CHAP correctly.  And again, FreeRADIUS is just handing the MS-CHAP data to Samba, and having Samba authenticate it.

Not able to get ntlm_auth working, I switched now to krb5. 'radtest' says:

***

root at hermes:~# radtest om topsecret localhost 0 testing123
Sent Access-Request Id 34 from 0.0.0.0:41742 to 127.0.0.1:1812 length 72
	User-Name = "om"
	User-Password = "topsecret"
	NAS-IP-Address = 192.168.6.1
	NAS-Port = 0
	Message-Authenticator = 0x00
	Cleartext-Password = "topsecret"
Received Access-Accept Id 34 from 127.0.0.1:1812 to 0.0.0.0:0 length 20

***

And the debug output is:

May I ignore the "PAP WARNINGS"? And will wireless clients (or the
users) authenticate if 'radtest' (via ssh) is successfull?
