PAM 0.99.3.0 update notes - pam_stack module depreciation The pam_stack module is now deprecated. It has to be replaced by include directives in pam.d configuration files. pam_stack usage won't make pam fail in this release, but it will be removed in a future release, better avoid it. It's basically a matter of replacing "required pam_stack.so service=" with "include ". This can't be automatically updated on system-edited configuration files because it isn't always that simple. Some "sufficient" directives in the included file may now occult directives that were previously matched, in the same configuration phase (auth/account/password/session). So, the rules may have to be reordered, and the "include" directives have often to be lowered at the bottom of each phase.
