## NAME
       pam_sm_acct_mgmt - PAM service function for account management

## SYNOPSIS
       **#include** **<security/pam**___**modules.h>**

       **int** **pam**___**sm**___**acct**___**mgmt(pam**___**handle**___**t** *****_pamh_**,** **int** _flags_**,** **int** _argc_**,** **const** **char** ******_argv_**);**

## DESCRIPTION
       The **pam**___**sm**___**acct**___**mgmt** function is the service module's implementation of the **pam**___**acct**___**[mgmt**(3)](https://www.chedong.com/phpMan.php/man/mgmt/3/markdown)
       interface.

       This function performs the task of establishing whether the user is permitted to gain access
       at this time. It should be understood that the user has previously been validated by an
       authentication module. This function checks for other things. Such things might be: the time
       of day or the date, the terminal line, remote hostname, etc. This function may also determine
       things like the expiration on passwords, and respond that the user change it before
       continuing.

       Valid flags, which may be logically OR'd with _PAM_SILENT_, are:

       PAM_SILENT
           Do not emit any messages.

       PAM_DISALLOW_NULL_AUTHTOK
           Return **PAM**___**AUTH**___**ERR** if the database of authentication tokens for this authentication
           mechanism has a _NULL_ entry for the user.

## RETURN VALUES
       PAM_ACCT_EXPIRED
           User account has expired.

       PAM_AUTH_ERR
           Authentication failure.

       PAM_NEW_AUTHTOK_REQD
           The user's authentication token has expired. Before calling this function again the
           application will arrange for a new one to be given. This will likely result in a call to
           **pam**___**sm**___**chauthtok()**.

       PAM_PERM_DENIED
           Permission denied.

       PAM_SUCCESS
           The authentication token was successfully updated.

       PAM_USER_UNKNOWN
           User unknown to password service.
