This is what i do in my sidebar (in WP and BB):

<form action="<?php bloginfo('url') ?>/wp-login.php" method="post">

<label for="log">Usuario<br /><input type="text" name="log" id="log" value="" size="22" /></label>

<label for="pwd">Password<br /><input type="password" name="pwd" id="pwd" size="22" /></label>

<input type="submit" name="submit" value="Ingresar" class="button" />

<label for="rememberme"><small><input name="rememberme" id="rememberme" type="checkbox" checked="checked" value="forever" /> Recordarme</small></label><br />

<input type="hidden" name="redirect_to" value="<?php echo $_SERVER['REQUEST_URI']; ?>"/>

</form>
