Date: Fri, 20 Jan 2006 11:34:51 -0000
Hi everybody,
I'm trying to authenticate users login in a machine using ssh. I 
have configured ssh & PAM on that server to autenticate against the 
radius server (Redhat Application Server 2.1).
Please find below the debug of the radius server as well as my conf files.
The Free radius server says :
Login incorrect: [test/\010\n\INCORRECT] (from client 
us067.eudra.org port 1500 cli 192.168.xx.xx)
   WARNING: Unprintable characters in the password. ?  Double-check 
the shared secret on the server and the NAS!
So did I . I checked the secrets on the server and they are *IDENTICAL*...
I used the NTRadPing utility with exactly the same parameters and 
it works absolutely fine !
Thank you for your help !
my /etc/raddb/server file : (on the client machine) :
[root@us067 root]# vi /etc/raddb/server
#  pam_radius_auth configuration file.  Copy to: /etc/raddb/server
#
#  For proper security, this file SHOULD have permissions 0600,
#  that is readable by root, and NO ONE else.  If anyone other than
#  root can read this file, then they can spoof responses from the server!
#
#  There are 3 fields per line in this file.  There may be multiple
#  lines.  Blank lines or lines beginning with '#' are treated as
#  comments, and are ignored.  The fields are:
#
#  server[:port] secret [timeout]
#
#  the port name or number is optional.  The default port name is
#  "radius", and is looked up from /etc/services The timeout field is
#  optional.  The default timeout is 3 seconds.
#
#  If multiple RADIUS server lines exist, they are tried in order.  The
#  first server to return success or failure causes the module to return
#  success or failure.  Only if a server fails to response is it skipped,
#  and the next server in turn is used.
#
#  The timeout field controls how many seconds the module waits before
#  deciding that the server has failed to respond.
#
# server[:port] shared_secret      timeout (s)

# having localhost in your radius configuration is a Good Thing.
