PAM-AUTH-UPDATE(8) System Manager's Manual PAM-AUTH-UPDATE(8)
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 en-
able; 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 stan-
dard 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 mod-
ifications 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 de-
bconf 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 pro-
files that are not on by default.
--remove profile [profile...]
Remove the specified profiles from the system configuration. pam-auth-update --re-
move 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 us-
able 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.
