NAME

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

SYNOPSIS

       pam-auth-update [--package [--remove profile [profile...]]]  [--force]

DESCRIPTION

       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.

OPTIONS

       --package
              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.

       --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.

       --force
              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.

FILES

       /etc/pam.d/common-*
           Global configuration of PAM, affecting all installed services.

       /usr/share/pam-configs/
           Package-supplied authentication profiles.
