Hello everyone,
I’m trying to bring up a fresh instance using 2.2.0, rather than just cloning
old 1.x configs as has been done in previous upgrades. In building a new Ubuntu
server, I grabbed the latest available build of samba (3.6.3); I’ve read that a
version of at least version 3.5.4 is required to work with Windows Server 2008
r2 AD. Compatibility with 2008 r2 is what is driving this upgrade.
Working from the Deploying Radius site, I’ve made good progress. So far, the
directions have been clear and everything has worked well. I even took the
opportunity to learn mercurial along the way… thanks ☺. I also created two
virtual servers, to support different policies for our main campus wireless and
eduroam. That also seems to be working well, with one SSID pointing to each
virtual server… slick!
Ntlm works:
/usr/bin/ntlm_auth --request-nt-key --domain=COLOSTATE --username=slovaas
password:
NT_STATUS_OK: Success (0x0)
root@freerad13:/etc/freeradius/modules#
Winbind looks OK, though only the challenge/response version of authentication…
that’s normal?:
wbinfo -a slovaas
Enter slovaas's password:
plaintext password authentication failed
Could not authenticate user slovaas with plaintext password
Enter slovaas's password:
challenge/response password authentication succeeded
root@freerad13:/etc/freeradius#
And with a forced default ntlm_auth in the users file, I can authenticate with
radtest.
But here’s where I’m stuck. When I remove the default ntlm_auth line in the
users file and put the ntlm_auth line in mschap, I no longer get access_accept.
The debug of the request is pasted below. But I wondered… basic authentication
is working (with ntlm_auth) but mschap doesn’t get what it wants back (using
ntlm_auth), which sounds like an issue that was around in earlier versions of
samba. Before I go downgrading samba, though, I was wondering if anyone saw
anything I missed or had any other suggestions.
Thanks,
Steve
