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

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. SunOS 5.11 13 Oct 1998 pam_open_session(3PAM)

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
