pam-auth-update [--package [--remove profile [profile...]]] [--force]
pam-auth-update is a utility that permits configuring the central authentication policy for the system using pre-defined profiles as supplied by PAM module packages. Profiles shipped in the /usr/share/pam-configs/ directory specify the modules, with options, to enable; the preferred ordering with respect to other profiles; and whether a profile should be enabled by default. Packages providing PAM modules register their profiles at install time by calling pam-auth-update --package. Selection of profiles is done using the standard debconf interface. The profile selection question will be asked at `medium' priority when packages are added or removed, so no user interaction is required by default. Users may invoke pam-auth-update directly to change their authentication configuration.
The script makes every effort to respect local changes to /etc/pam.d/common-*. Local modifications to the list of module options will be preserved, and additions of modules within the managed portion of the stack will cause pam-auth-update to treat the config files as locally modified and not make further changes to the config files unless given the --force option.
If the user specifies that pam-auth-update should override local configuration changes, the locally-modified files will be saved in /etc/pam.d/ with a suffix of .pam-old.
