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 themself 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.
