pam_sm_acct_mgmt(3PAM) PAM Library Functions pam_sm_acct_mgmt(3PAM)
NAME
pam_sm_acct_mgmt - service provider implementation for pam_acct_mgmt
SYNOPSIS
cc [ flag ... ] file ... -lpam [ library ... ]
#include <security/pam_appl.h>
#include <security/pam_modules.h>
int pam_sm_acct_mgmt(pam_handle_t *pamh, int flags, int argc,
const char **argv);
DESCRIPTION
In response to a call to pam_acct_mgmt(3PAM), the PAM framework calls pam_sm_acct_mgmt() from the modules listed in the pam.conf(4) file.
The account management provider supplies the back-end functionality for this interface function. Applications should not call this API
directly.
The pam_sm_acct_mgmt() function determines whether or not the current user's account and password are valid. This includes checking for
password and account expiration, and valid login times. The user in question is specified by a prior call to pam_start(), and is referenced
by the authentication handle, pamh, which is passed as the first argument to pam_sm_acct_mgmt(). 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.
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 account management service. Please refer to the specific module man pages for the var-
ious available options. If an unknown option is passed to the module, an error should be logged through syslog(3C) and the option ignored.
If an account management module determines that the user password has aged or expired, it should save this information as state in the
authentication handle, pamh, using pam_set_data(). pam_chauthok() uses this information to determine which passwords have expired.
RETURN VALUES
If there are no restrictions to logging in, PAM_SUCCESS is returned. The following error values may also be returned upon error:
PAM_USER_UNKNOWN User not known to underlying authentication module.
PAM_NEW_AUTHTOK_REQD New authentication token required.
PAM_ACCT_EXPIRED User account has expired.
PAM_PERM_DENIED User denied access to account at this time.
PAM_IGNORE Ignore underlying account module regardless of whether the control flag is required, optional or sufficient.

NOTES
The interfaces in libpam are MT-Safe only if each thread within the multithreaded application uses its own PAM handle.
If the PAM_REPOSITORY item_type is set and a service module does not recognize the type, the service module does not process any informa-
tion, and returns PAM_IGNORE. If the PAM_REPOSITORY item_type is not set, a service module performs its default action.
