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 function-
     ality  for  only one PAM category: that of authentication.  In terms of the
     module-type parameter, this is the "auth" feature.  It also provides 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) cre-
     dentials.	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 hypothet-
		   ical 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.
