<h2>Background</h2>

<p>All of the web pages and scripts that TIM Enterprise serves are protected by a login that is provided by a user when entering their username and password into a pop-up dialog in their web browser.</p>

<p>In some situations, it is desirable to suppress this dialog box demanding the username and password.  An example might be the deployment of a stand-alone computer displaying a pre-defined wallboard on a large screen; it would become tedious having to log in to the web page every time that computer is restarted.</p>

<p>Different web browsers behave differently for automatic logging-in to  web pages.  Variously, they range from complete prohibition of the practise, to permitting it if certain system parameters are configured.</p>

<h2>Specifics</h2>

<p>In this article, details of how to allow automatic logging-in to a 
web page concerns the Microsoft Internet Explorer (version 6 and above) 
browsers only.  Please consult your browser documentation for a solution
 related to your own choice of browser.</p>


<p>The solution involves creating a specially-crafted URL in the following form:-</p>

http://username:password@serverhost/

<h2>Solution</h2>

<p>Although including the username and password in a URL is disabled by 
default on Windows Internet Explorer since it is considered a security 
risk, you can override this restriction by making the following changes 
to the Windows Registry.</p>

WARNING! Since you'll be exposing a username and password as part of a URL, it is recommended that you create a dedicated web user object inside the TIM Enterprise directory that will be used solely for this purpose.  See Adding/Removing Web Users for details of how to set up a web user.

<p>Open Windows Registry Editor, <span class="keyword">REGEDIT.EXE</span>, from the Windows <span class="keyword">Start Menu ? Run</span>.  Locate the following registry key:-</p>

HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_HTTP_USERNAME_PASSWORD_DISABLE

Inside this registry key, add the following <span class="keyword">DWORD</span> entries:-

IEXPLORE.EXE  (Set DWORD value to 0, zero)
EXPLORER.EXE  (Set DWORD value to 0, zero)

<p>Close the Registry Editor and create a bookmark in Internet Explorer, specifying the URL as per the following example:-</p>

http://USERNAME:PASSWORD@HOSTNAME/display/?suiv=12345

<p>Replace the following items:-</p>

<ul>
	<li><span class="keyword">USERNAME</span> replace with the username of the web user you use to access the page</li>
	<li><span class="keyword">PASSWORD</span> replace with the password of the web user you use to access the page</li>
	<li><span class="keyword">HOSTNAME</span> replace with the host name or IP address of the machine running TIM Enterprise</li>
</ul>
