Dear All, I am testing RADIUS protocol implementation - freeradius, on RedHat Linux 7.2 platform, after using some shipped tools with freeradius package to test it is working normally. Nest step I want to combine RADIUS with pam to provide some additional functions to other service, i.e., login. But I do not know how to configure it. The following list is the detail information about this test, 1. Hardware Platform: Intel x386 2. Operating System: RedHat Linux 7.2 3. RADIUS daemon: freeradius-0.8.1 4. Linux-PAM: pam-0.75-46.7.2 5. Others: pam_radius_auth.so, pam_radius_auth.conf 6. Testing radiusd function, [root@xxxxxxxx bin]# ./radtest Clarke 123abc# 202.123.194.30 1812 testing123 Sending Access-Request of id 146 to 202.123.194.30:1812 User-Name = "Clarke" User-Password = "\254O\236\262\373.\000\r\321,\214sE\334u\030" NAS-IP-Address = RedHat-7.2 NAS-Port = 1812 rad_recv: Access-Accept packet from host 202.123.194.30:1812, id=146, length=20 7. Copy pam_radius_auth.so to /lib/security 8. Reconfig /etc/pam.d/login file as following auth required /lib/security/pam_securetty.so auth sufficient /lib/security/pam_radius_auth.so auth required /lib/security/pam_unix_auth.so 9. Use telnetd service call for login service, but it don't work Is there any suggestion for this case? Thank you!
