PAM Library Functionspam_sm_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

 

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

NOTES

 

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