/etc/pam.d/su wants pam_stack.s
Last modified: 2008-05-01 11:37:57 EDT
After an upgrade from RH 6.2, su quits working and reports the following: Jul 31 17:21:52 Omega su: PAM unable to dlopen(/lib/security/pam_stack.so) Jul 31 17:21:52 Omega su: PAM [dlerror: /lib/security/pam_stack.so: cannot open shared object file: No such file or directory] Jul 31 17:21:52 Omega su: PAM adding faulty module: /lib/security/pam_stack.so /etc/pam.d/su included with rpm wants pam_stack.so which doesn't exist in my distribution. Maybe needs a dependency for the package that has pam_stack.so in rpm? Replacing /etc/pam.d/su with the old 6.2 file works around the problem. /etc/pam.d/su from pinstripe rpm: #%PAM-1.0 auth sufficient /lib/security/pam_rootok.so # Uncomment the following line to implicitly trust users in the "wheel" group. #auth sufficient /lib/security/pam_wheel.so trust use_uid # Uncomment the following line to require a user to be in the "wheel" group. #auth required /lib/security/pam_wheel.so use_uid auth required /lib/security/pam_stack.so service=system-auth account required /lib/security/pam_stack.so service=system-auth password required /lib/security/pam_stack.so service=system-auth session required /lib/security/pam_stack.so service=system-auth session optional /lib/security/pam_xauth.so /etc/pam.d/su from 6.2 distribution:#%PAM-1.0 auth required /lib/security/pam_pwdb.so shadow nullok account required /lib/security/pam_pwdb.so password required /lib/security/pam_cracklib.so password required /lib/security/pam_pwdb.so shadow use_authtok nullok session required /lib/security/pam_pwdb.so session optional /lib/security/pam_xauth.so
Sorry... it looks like my rpm database is corrupted. Whether the corruption was caused by the upgrade is unknown but in any case I'm going to do a fresh install with pinstripe.
