    <para>
      The <function>pam_sm_acct_mgmt</function> function is the service
      module's implementation of the
      <citerefentry>
        <refentrytitle>pam_acct_mgmt</refentrytitle><manvolnum>3</manvolnum>
      </citerefentry> interface.

    <para>
      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.

            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
            <function>pam_sm_chauthtok()</function>.
