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 various 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.
