Thanks for the hint.

<br>Are there some more things to think about?<br>Best Regards<br>Ernst<br><br><br><br><div class="gmail_quote">2010/2/8 Brian Vuyk <span dir="ltr"><<a href="mailto:brian@brianvuyk.com">brian@brianvuyk.com</a>></span><br>

Is it possible this could be simplified somewhat by using
user_external_login()?<br>

I've written a patch for the ip_login module. It extends the module
with the possiblity to have a "login as an other user" link.<br>
<br>
Basically it does the following things:<br>
<ol>
<li>Logs out the current user.</li>
<li>Makes sure ip_login does not straight login again.</li>
<li>Shows the user login screen.</li>
</ol>
My code works, but I'm not 100% sure whether it's save to code it like
that. Could someone have an I on it?<br>
