NAME

       pam_setcred - modify/delete user credentials for an authentication service

SYNOPSIS

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

       int pam_setcred(pam_handle_t *pamh, int flags);

DESCRIPTION

       The pam_setcred() function is used to establish, modify, or delete user credentials. It is typically called after the user has been authen-
       ticated and after a session has been opened. See pam_authenticate(3PAM), pam_acct_mgmt(3PAM), and pam_open_session(3PAM).

       The user is specified by a prior call to pam_start() or pam_set_item(), and is referenced by the authentication handle, pamh. The following
       flags may be set in the flags field.  Note that the first four flags are mutually exclusive:

       PAM_ESTABLISH_CRED	       Set user credentials for an authentication service.

       PAM_DELETE_CRED		       Delete user credentials associated with an authentication service.

       PAM_REINITIALIZE_CRED	       Reinitialize user credentials.

       PAM_REFRESH_CRED 	       Extend lifetime of user credentials.

       PAM_SILENT		       Authentication service should not generate any messages.

       If no flag is set,  PAM_ESTABLISH_CRED is used as the default.

RETURN VALUES

       Upon success, pam_setcred() returns  PAM_SUCCESS. In addition to the error return values described in pam(3PAM) the following values may be
       returned upon error:

       PAM_CRED_UNAVAIL 	       Underlying authentication service can not retrieve user credentials unavailable.

       PAM_CRED_EXPIRED 	       User credentials expired.

       PAM_USER_UNKNOWN 	       User unknown to underlying authentication service.

       PAM_CRED_ERR		       Failure setting user credentials.

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.
