PAM_ACCT_MGMT(3)	       Linux-PAM Manual		      PAM_ACCT_MGMT(3)

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.
