NAME
pam-auth-update - manage PAM configuration using packaged profiles
SYNOPSIS
pam-auth-update [--package [--remove profile [profile...]]] [--force] [--enable profile [pro‐
file...]] [--disable profile [profile...]]
DESCRIPTION
pam-auth-update is a utility that permits configuring the central authentication policy for the sys‐
tem 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 order‐
ing 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 re‐
quired by default. Users may invoke pam-auth-update directly to change their authentication configu‐
ration.
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 ques‐
tions to `medium' so that the user is not prompted by default.
--disable profile [profile...]
Disable the specified profiles in system configuration. This can be used from system adminis‐
tration scripts to disable profiles.
--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 re‐
moved 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.
