> Is the user in /etc/passwd and /etc/shadow?
Yes
>If so, check permissions
/etc/shadow was chgrp'd to radiusd in spite of John Dennis' warnings to the
contrary --
BUT I forgot to change the read permission -- my fault totally --
>Which file did I tell you to modify?
modules/passwd edited as follows:
passwd {
filename = /etc/shadow
format = "*User-Name::Crypt-Password::::::"
hashsize = 100
ignorenislike = no
allowmultiplekeys = no
and site-enabled/default edited to include passwd in the authorize section
and voila' it works -- thanks!! --- BUT ------
you and John Dennis both mentioned PAM so I went ahead and commented out the
passwd entires and I am now looking at PAM per your suggestion.
Installed the pam-radius client per
http://freeradius.org/pam_radius_auth/
and made the changes to /etc/pam.d/.
Created the file /etc/raddb/server and uncommented pam from
sites-enabled/default.
Added Default Auth-Type = PAM to the users file.
Now I get this output after running radtest
rad_recv: Access-Request packet from host 127.0.0.1 port 49068, id=108,
length=56
User-Name = "test"
User-Password = "password"

NAS-Port = 0
+- entering group authorize {...}

Delaying reject of request 0 for 1 seconds
Going to the next request
Waking up in 0.9 seconds.
Sending delayed reject for request 0
Sending Access-Reject of id 108 to 127.0.0.1 port 49068
Waking up in 4.9 seconds.
Cleaning up request 0 ID 108 with timestamp +6
Ready to process requests.
Not sure why it sez "pam_pass: using pamauth string <radiusd> for pam.conf
lookup" whne it is set to look at /etc/pam.d/radiusd
Thoughts?
many thanks in advance
radiusd -X now yields:
