Hi,

I've been following the new instructions on how to set up a test service 
on Centos. I'm using standard Centos 6.4 and as far as I can tell have 
followed the instructions detailed on the wiki[1] to the letter but it 
doesn't appear to work.

radiusd appears to start up OK (I've included the output of it running 
in debug as an attachment) but gss-server doesn't appear to want to talk 
to it at all. I'm running the command:

gss-server -verbose -logfile /tmp/gss-server.log 
[log in to unmask] & to initiate the gss-server

I then run:

gss-client -mech "{1.3.6.1.5.5.15.1.1.18 }" 127.0.0.1 
[log in to unmask] bar

This generates the following output:
Sending init_sec_context token (size=53)...continue needed...
CTRL-EVENT-EAP-STARTED EAP authentication started
Sending init_sec_context token (size=29)...continue needed...
GSS-API error initializing context: Unspecified GSS failure.  Minor code 
may provide more information
GSS-API error initializing context: Generic RADIUS failure

The output of /tmp/gss-server.log is:

tail /tmp/gss-server.log
73 68 6f 74 2d 74 65 73 74 2e 69 73 2e 65 64 2e
61 63 2e 75 6b 80 00 00 05 00 00 00 05 01 00 00
05 01
continue needed...

00 00 04 00 00 00 06 02 00 00 06 01 40
Sending accept_sec_context token (size=31):
60 1d 06 09 2b 06 01 05 05 0f 01 01 12 06 02 80
00 00 01 00 00 00 08 00 0d 00 00 00 00 00 10

Running either gss-server or gss-client results in no additional output 
to radiusd beyond that which I've attached which makes me think that it 
isn't talking to radius at all but I've no idea why.

I should add that I have set GSSAPIStrictAcceptorCheck to no in 
/etc/ssh/sshd_config.
