       pam-auth-update - manage PAM configuration using packaged profiles

       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 sup-
       plied    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 con-
       figuration  changes,  the  locally-modified  files  will  be  saved  in
       /etc/pam.d/ with a suffix of .pam-old.

              Indicate  that the caller is a package maintainer script; lowers
              the priority of debconf questions to `medium' so that  the  user
              is not prompted by default.

       --enable profile [profile...]
              Enable  the  specified profiles in system configuration. This is
              used to enable profiles that are not on by default.

       --remove profile [profile...]
              Remove the specified profiles  from  the  system  configuration.
              pam-auth-update  --remove should be used to remove profiles from
              the configuration before the modules they reference are  removed
              from  disk,  to  ensure  that  PAM is in a consistent and usable
              state at all times during package upgrades or removals.

              Overwrite the  current  PAM  configuration,  without  prompting.
              This  option  must not be used by package maintainer scripts; it
              is intended for use by administrators only.

           Global configuration of PAM, affecting all installed services.

           Package-supplied authentication profiles.
