Hi there list,
Am in the process of using FreeRadius for 802.1x authentication and ran
into some problems with peap and mschap2.
FreeRADIUS Version 2.1.10, for host x86_64-pc-linux-gnu, built on Nov 24
2011 at 07:53:12
Ubuntu 64bit 12.04 (wheezy/sid)
winbindd version 3.6.3
Ntlm_auth seems to work just fine:
pkn@radtest:~$ ntlm_auth -request-ne-key --domain=ATLAS
--username=osgtest
password:
NT_STATUS_NO_SUCH_USER: No such user (0xc0000064)
Which is just fine... that user indeed does not exist.
pkn@radtest:~$ ntlm_auth -request-ne-key --domain=ATLAS
--username=stafosg
password:
NT_STATUS_OK: Success (0x0)
Good user and pass... no problem...
pkn@radtest:~$ ntlm_auth -request-ne-key --domain=ATLAS
--username=stafosg
password:
NT_STATUS_WRONG_PASSWORD: Wrong Password (0xc000006a)
Good user wrong pass... again no problem there
But radtest gives the following:
pkn@radtest:~$ radtest -t mschap stafosg ****** localhost 0 testing123
Sending Access-Request of id 183 to 127.0.0.1 port 1812
User-Name = "stafosg"
NAS-IP-Address = 127.0.1.1
NAS-Port = 0
MS-CHAP-Challenge = 0x7f1105068ad7bc78
MS-CHAP-Response =
0x00010000000000000000000000000000000000000000000000000f03251526c7384a3b
76762e76c823a1ca6bd195649817d4
rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=183,

And the following freeradius -X trace:

The thing that bugs me is:
Exec-Program output: Reading winbind reply failed! (0xc0000001) which
seems to indicate that I have insufficient right to winbindd-privileged.
But I cannot find the socket (?) anywhere.
Or am I experiencing the Samba bug? Reading the list it looked like that
one is fixed in current Samba releases?
Any help will be appreciated...
