pam radius authentication
Hello!
I try to authenticate ssh users logins using pam_radius_auth.so.
On my RedHat 9 I have the following setup:
- freeradius server
- users file:
test Auth-Type := Local, User-Password == "test"
- clients.conf
client 127.0.0.1 {
secret = secret
shortname = localhost
}
-pam radius module
- cat /etc/pam.d/sshd
#%PAM-1.0
auth required pam_securetty.so
auth sufficient pam_radius_auth.so debug
auth required /lib/security/pam_unix_auth.so
account required pam_radius_auth.so debug
password required pam_stack.so service=system-auth
session required pam_stack.so service=system-auth
session required pam_limits.so
session optional pam_console.so
-cat /etc/raddb/server
127.0.0.1 secret 1
- pam_radius_auth.so is copied in /lib/security
-I created linux user test with home directory /home/test , without setting up a
password
- freeradius started with radiusd -X
Problem is that, when I trie to connect to this machine using ssh, the radius se
rver receives the request, processes it, sends access-accept, but the ssh sessio
n is ended, without the user being really logged in !!! I don't know the reason
why the user gets rejected...
