Setting up pam_radius_auth

[Mike J]

Hi,

I'm trying to get the the pam radius module to work.
I've built a test radius server (FreeRADIUS Version 2.1.9) and I've setup a
linux box with the pam radius module (1.3.17)


The server seems to be setup properly to authenticate users:

# radtest testing password 127.0.0.1 0 testing123
Sending Access-Request of id 87 to 127.0.0.1 port 1812
    User-Name = "testing"
    User-Password = "password"
    NAS-IP-Address = 127.0.1.1
    NAS-Port = 0
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=87,
length=20


I have the following config on the server to correspond to my pam radius
client:

clients.conf:
client testclient1 {
        ipaddr = CLIENTIP

        secret          = testing123

        require_message_authenticator = no

        shortname       = testc1

        nastype     = other     # localhost isn't usually a NAS...

}

And on the client (using pam_radius_auth) I have the following in
/etc/raddb/server:

# server[:port]    shared_secret      timeout (s)
SERVERIP  testing123 4

Now, when I try to authenticate my pam radius client, I get this in the
client logs:

Jul 22 10:22:45 (none) pamtest: pam_radius_auth: Got user name testing
Jul 22 10:22:54 (none) pamtest: pam_radius_auth: Sending RADIUS request code

Jul 22 10:22:55 (none) pamtest: pam_radius_auth: All RADIUS servers failed

Jul 22 10:22:55 (none) pamtest: pam_radius_auth: authentication failed


And I get this on the radius server (running in debug mode, i.e. radiusd -X)
rad_recv: Access-Request packet from host CLIENTIP port 18580, id=32,

    User-Name = "testing"

Now obviously is says there's a problem with the secret, but I believe I've
setup the secret correctly in the configs I've shown above.
Does anybody have any ideas what I'm doing wrong?

Thanks.
