I have a situation where I am trying to enable radius authentication for issuing the su command. I've added the ruser command to attempt to pull back the PAM_RUSER who is issuing the su command. However, from the debug logs, I can still see that it says Got user root. Immediately after that line in the debug, it actually does a Segmentation Fault and throws a core dump. On the user's side logging in, it prompts for password as expected, and then after entering, just comes back with su: Segmentation Fault. The OS is solaris 10. Any ideas? Thanks!
