Here is what I found to be suitable based on Jason Purdy's suggestion.
DISCLAMER: I am not a very knowledgeable perl programmer - so
suggestions to improve it would be deeply appreciated. This is tested
code;

I have two run-modes 'login' and 'logout' used in the usual
CAP::Authentication style. Here is my prerun in the super-class:

sub cgiapp_prerun {
	my $app = shift;
	my $rm = shift;
	return if ($rm eq 'login') || ($rm eq 'logout');
	my $set_status = sub {
		my ($c, $ht_params, $tmpl_params, $tmpl_file) = @_;
		%$tmpl_params = (
			USERNAME => $app->authen->username,
			LASTLOGIN => $app->authen->last_login,
			THISURL => $app->query->url,
		);
	};
	$app->add_callback('load_tmpl', $set_status);
}

And here is my template fragment embedded inside every page:

<p class="authentication">
	<!-- TMPL_IF NAME=USERNAME -->
	Logged In As: <!-- TMPL_VAR NAME=USERNAME --> (<a
href="index.cgi?authen_logout=1">Logout</a>)<br />
	Last Login: <!-- TMPL_VAR NAME=LASTLOGIN -->
	<!-- TMPL_ELSE -->
	<form  id="loginform" name="loginform" method="post" action="<!--
TMPL_VAR NAME=THISURL -->">
		<p>
			<!-- TMPL_IF NAME=ATTEMPTS -->
				Username or Password is Incorrect. Please enter the Username and
Password assigned to you by the Administrator.
				(Attempt #: <!-- TMPL_VAR NAME=ATTEMPTS -->)
			<!-- /TMPL_IF -->
			<label for="authen_username"><em>*</em>Username:</label>
			<input class="textInput" tabindex="1" type="text"
name="authen_username" size="20" value="" /><br />
			<label for="authen_password"><em>*</em>Password:</label>
			<input class="textInput" tabindex="2" type="password"
name="authen_password" size="20" /><br />
			<div class="submitblock"><input class="primaryAction" tabindex="4"
type="submit" name="authen_loginbutton" value="Sign In"
class="button" /> or <a href="#">Register</a></div>
		</p>
		<input type="hidden" name="destination" value="<!-- TMPL_VAR
NAME=THISURL -->" />
		<input type="hidden" name="rm" value="authen_login" />
	</form>
	<!-- /TMPL_IF -->	
</p>

Any suggestions would be welcome and deeply appreciated!
