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 users 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.
