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.

ATTRIBUTES

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.

pam_acct_mgmt(3PAM)					       PAM Library Functions					       pam_acct_mgmt(3PAM)

NAME

       pam_acct_mgmt - perform PAM account validation procedures

SYNOPSIS

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

       int pam_acct_mgmt(pam_handle_t *pamh, int flags);

DESCRIPTION

       The pam_acct_mgmt() function is called to determine if the current user's account is valid.  It checks for password and account expiration,
       and verifies access hour restrictions.
	This function is typically called after the user has been authenticated with pam_authenticate(3PAM).

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

       PAM_SILENT		       The account management service should not generate any messages.

       PAM_DISALLOW_NULL_AUTHTOK       The account management service should return PAM_NEW_AUTHTOK_REQD if the user  has  a  null  authentication
				       token.

RETURN VALUES

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

       PAM_USER_UNKNOWN 	       User not known to underlying account management module.

       PAM_AUTH_ERR		       Authentication failure.

       PAM_NEW_AUTHTOK_REQD	       New authentication token required. This is normally returned if the machine security policies require  that
				       the password should be changed because the password is  NULL or has aged.

       PAM_ACCT_EXPIRED 	       User account has expired.

ATTRIBUTES

       |Interface Stability	     | Stable			   |
