# Configuration file for Pluggable Authentication Modules (PAM).
#
# This file controls the authentication methods that login and other
# utilities use.  See pam(8) for a description of its format.

#
# service-name	module-type	control-flag	module-path	arguments
#
# module-type:
#  auth:      prompt for a password to authenticate that the user is
#             who they say they are, and set any credentials.
#  account:   non-authentication based authorization, based on time,
#             resources, etc.
#  session:   housekeeping before and/or after login.
#  password:  update authentication tokens.
#
# control-flag: How libpam handles success or failure of the module.
#  required:   success is required, and on failure all remaining
#              modules are run.
#  requisite:  success is required, and on failure no remaining
#              modules are run.
#  sufficient: success is sufficient, and if no previous required
#              module failed, no remaining modules are run.
#  optional:   ignored unless the other modules return PAM_IGNORE.
#
# arguments:
#  Passed to the module; module-specific plus some generic ones:
#   debug:           syslog debug info.
#   no_warn:         return no warning messages to the application.
#   use_first_pass:  try authentication using password from the
#                    preceding auth module.
#   try_first_pass:  first try authentication using password from
#                    the preceding auth module, and if that fails
#                    prompt for a new password.
#   use_mapped_pass: convert cleartext password to a crypto key.
#   expose_account:  allow printing more info about the user when
#                    prompting.
#
# Each final entry must say "required" -- otherwise, things don't
# work quite right.  If you delete a final entry, be sure to change
# "sufficient" to "required" in the entry before it.
