PAM_OPIE(8)		    System Manager's Manual		   PAM_OPIE(8)

NAME
       pam_opie	-- OPIE	PAM module

SYNOPSIS
       [service-name] module-type control-flag pam_opie	[options]

DESCRIPTION
       The OPIE	authentication service module for PAM, pam_opie	provides func-
       tionality  for only one PAM category: that of authentication.  In terms
       of the module-type parameter, this is the "auth"	feature.  It also pro-
       vides a null function for session management.

       Note that this module does not enforce opieaccess(5) checks.  There  is
       a separate module, pam_opieaccess(8), for this purpose.

   OPIE	Authentication Module
       The  OPIE  authentication  component  provides  functions to verify the
       identity	of a user (pam_sm_authenticate()), which obtains the  relevant
       opie(4)	credentials.  It provides the user with	an OPIE	challenge, and
       verifies	that this is correct with opiechallenge(3).

       The following options may be passed to the authentication module:

       debug	     syslog(3) debugging information at	LOG_DEBUG level.

       auth_as_self  This option will require the user to authenticate himself
		     as	the user given by getlogin(2), not as the account they
		     are attempting to access.	This is	primarily for services
		     like su(1), where the user's ability to retype their  own
		     password might be deemed sufficient.

       no_fake_prompts
		     Do	not generate fake challenges for users who do not have
		     an	 OPIE  key.   Note that	this can leak information to a
		     hypothetical attacker about who uses OPIE	and  who  does
		     not,  but	it  can	 be useful on systems where some users
		     want to use OPIE but most do not.

       Note that pam_opie ignores  the	standard  options  try_first_pass  and
       use_first_pass, since a challenge must be generated before the user can
       submit a	valid response.

FILES
       /etc/opiekeys  default OPIE password database.
