In pam-0.68-1, /lib/security/pam_unix.so references the symbol yperr_string, which leads to messages like the following in /var/log/messages: Aug 14 01:24:34 dunwoody1 su: PAM unable to dlopen(/lib/security/pam_unix_acct.so) Aug 14 01:24:34 dunwoody1 su: PAM [dlerror: /lib/security/pam_unix_acct.so: undefined symbol: yperr_string] Aug 14 01:24:34 dunwoody1 su: PAM adding faulty module: /lib/security/pam_unix_acct.so I'm wondering if perhaps there is a new dependency from pam to some other package that I don't happen to have installed, and the pam-0.68-1 rpm doesn't enforce that dependency?
Fixed in pam-0.68-3 and later
