pam_open_session(3PAM)					       PAM Library Functions					    pam_open_session(3PAM)

NAME

       pam_open_session, pam_close_session - perform PAM session creation and termination operations

SYNOPSIS

       cc [ flag ... ] file ... -lpam [ library ... ]
       #include <security/pam_appl.h>

       int pam_open_session(pam_handle_t *pamh, int flags);

       int pam_close_session(pam_handle_t *pamh, int flags);

DESCRIPTION

       The   pam_open_session()   function  is	called	after  a  user	has  been  successfully  authenticated.  See   pam_authenticate(3PAM)  and
       pam_acct_mgmt(3PAM).  It is used to notify the session modules that a  new  session   has  been	initiated.   All  programs  that  use  the
       pam(3PAM)  library  should  invoke  pam_open_session() when beginning a new session. Upon termination of this activity, pam_close_session()
       should be invoked to inform pam(3PAM) that the session has terminated.

       The pamh argument is an authentication handle obtained by a prior call to pam_start(). The following flag may be set in the flags field for
       pam_open_session() and pam_close_session():

       PAM_SILENT      The session service should not generate any messages.

RETURN VALUES

       Upon  successful  completion,   PAM_SUCCESS is returned.  In addition to the return values defined in pam(3PAM), the following value may be
       returned on error:

       PAM_SESSION_ERR	       Cannot make or remove an entry for the specified session.

NOTES

       In many instances, the pam_open_session() and pam_close_session() calls may be made by different processes. For example, in UNIX the  login
       process	opens  a  session,  while  the	init  process closes the session.  In this case, UTMP/WTMP entries may be used to link the call to
       pam_close_session() with an earlier call to pam_open_session(). This is possible because UTMP/WTMP entries are  uniquely  identified  by  a
       combination  of	attributes, including the user login name and device name, which are accessible through the  PAM handle, pamh. The call to
       pam_open_session() should precede  UTMP/WTMP entry management, and the call to pam_close_session() should follow   UTMP/WTMP  exit  manage-
       ment.

       The interfaces in  libpam are MT-Safe only if each thread within the multithreaded application uses its own  PAM handle.

NAME

       pam_sm_open_session, pam_sm_close_session - service provider implementation for pam_open_session and pam_close_session

SYNOPSIS

       cc [ flag ... ]	file ... -lpam [ library ... ]
       #include <security/pam_appl.h>
       #include <security/pam_modules.h>

       int pam_sm_open_session(pam_handle_t *pamh, int flags, int argc, const char **argv);

       int pam_sm_close_session(pam_handle_t *pamh, int flags, int argc, const char **argv);

DESCRIPTION

       In  response  to  a  call  to  pam_open_session(3PAM)  and  pam_close_session(3PAM),  the   PAM	framework  calls pam_sm_open_session() and
       pam_sm_close_session(), respectively from the modules listed in the pam.conf(4) file.  The session management provider supplies	the  back-
       end functionality for this interface function.

       The  pam_sm_open_session()  function is called to initiate session management. Thepam_sm_close_session() function is invoked when a session
       has terminated. The argument pamh is an authentication handle. The following flag may be set in the flags field:

       PAM_SILENT      Session service should not generate any messages.

       The argc argument represents the number of module options passed in from the configuration file	pam.conf(4).  argv  specifies  the  module
       options,  which	are  interpreted  and  processed by the session management service.  If an unknown option is passed in, an error should be
       logged through syslog(3C) and the option ignored.

RETURN VALUES

       Upon successful completion,  PAM_SUCCESS should be returned. The following values may also be returned upon error:

       PAM_SESSION_ERR	       Cannot make or remove an entry for the specified session.

       PAM_IGNORE	       Ignore underlying session module regardless of whether the control  flag is required, optional or sufficient.

ATTRIBUTES

       See attributes(5) for description of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

       |Interface Stability	     | Stable			   |
       +-----------------------------+-----------------------------+
       |MT-Level		     |MT-Safe with exceptions	   |

NOTES

       The interfaces in  libpam are MT-Safe only if each thread within the multithreaded application uses its own  PAM handle.
