I'm running Suse 7.3 sparc. I noticed this message in my /var/log/messages today: Jun 21 12:45:19 dali PAM-unix2[2191]: auth: Unknown option: shadow My /etc/pam.d/pop3 is configured as follows: auth required /lib/security/pam_unix.so shadow nullok account required /lib/security/pam_unix.so session required /lib/security/pam_unix.so According to the documentation, pam_unix.so understands the "shadow" option. However, I also notice this: dali:~ # ls -li /lib/security/pam_unix.so /lib/security/pam_unix2.so 892956 -rwxr-xr-x 2 root root 50803 Feb 27 20:05 /lib/security/pam_unix.so 892956 -rwxr-xr-x 2 root root 50803 Feb 27 20:05 /lib/security/pam_unix2.so So pam_unix and pam_unix2 are the same. I read in the documentation that pam_unix2 is for handling NIS, and it doesn't know the "shadow" option. But why have the been linked as one? What if I'm not using NIS? -- Anand Buddhdev http://anand.org
