## NAME
       pam_acct_mgmt - PAM account validation management

## SYNOPSIS
### #include <security/pam_appl.h>


       **int pam_acct_mgmt(pam_handle_t *_**pamh_**, int _**flags_**);**

## DESCRIPTION
       The **pam_acct_mgmt **function is used to determine if the user's account is valid. It checks for
       authentication token and account expiration and verifies access restrictions. It is typically
       called after the user has been authenticated.

       The _pamh_ argument is an authentication handle obtained by a prior call to pam_start(). The
       flags argument is the binary or of zero or more of the following values:

       PAM_SILENT
           Do not emit any messages.

       PAM_DISALLOW_NULL_AUTHTOK
           The PAM module service should return PAM_NEW_AUTHTOK_REQD if the user has a null
           authentication token.

## RETURN VALUES
       PAM_ACCT_EXPIRED
           User account has expired.

       PAM_AUTH_ERR
           Authentication failure.

       PAM_NEW_AUTHTOK_REQD
           The user account is valid but their authentication token is _expired_. The correct response
           to this return-value is to require that the user satisfies the **pam_chauthtok() **function
           before obtaining service. It may not be possible for some applications to do this. In
           such cases, the user should be denied access until such time as they can update their
           password.

       PAM_PERM_DENIED
           Permission denied.

       PAM_SUCCESS
           The authentication token was successfully updated.

       PAM_USER_UNKNOWN
           User unknown to password service.
