Yes, Anonymous Access was checked but Integrated Windows Authentication was
unchecked.

Oh.  I totally missed that you were loading the whole layout.  I do not get
prompted in any of the three browsers with that, but Opera is totally
broken; doesn't show any images at all, including legend images.
That's OK; it's not a supported browser :)

What were the settings before you turned on integrated auth?  Anonymous
access?

Did some more investigation on this since Jason did not see the problem in
IE.  These pages work fine:
http://localhost/mapguide/mapviewernet/ajaxviewer.aspx?WEBLAYOUT=Library
%3a%
2f%2fSamples%2fSheboygan%2fLayouts%2fSheboyganAsp.WebLayout&USERNAME=Ano

http://localhost/mapguide/mapviewerphp/ajaxviewer.php?WEBLAYOUT=Library%
3a%2
f%2fSamples%2fSheboygan%2fLayouts%2fSheboyganAsp.WebLayout&USERNAME=Anon
ymou
s

But, when going through the configured mapviewerajax virtual directory using
the .NET web extension, I am prompted for a login.  Again, I can leave it
blank and say OK or Cancel and it opens fine.
http://localhost/mapguide/mapviewerajax/?WEBLAYOUT=Library%3a%2f%2fSampl
es%2
fSheboygan%2fLayouts%2fSheboyganAsp.WebLayout&USERNAME=Anonymous

http://data.mapguide.com/mapguide/mapviewerajax/?WEBLAYOUT=Library://Sam
ples
/Sheboygan/Layouts/SheboyganAsp.WebLayout&USERNAME=Anonymous

I changed the security settings on the mapviewerajax virtual directory in
IIS to use Integrated Windows Authentication and am now not prompted on a
Windows XP machine, but still am on a Windows 2003 Server.  It's definitely
an IIS / .NET web extensions issue.

You have downloaded the dotnetviewer sample from here?

https://mapguide.osgeo.org/files/documents/12/17/dotnetviewersample.zip

It basically initiates a session with a fixed userid and password:

     MapGuideApi.InitializeSockets();
     InitializeWebTier();
     MgUserInformation userInfo = new MgUserInformation("Anonymous", "");
     MgSite site = new MgSite();
     site.Open(userInfo);
     sessionId = site.CreateSession();
     MapGuideApi.TerminateSockets();

And then opens the ajax viewer in a frame:

    <frame src="/mapguide/mapviewernet/ajaxviewer.aspx?SESSION=<%=
sessionId %>&WEBLAYOUT=<%= webLayout %>" name="ViewerFrame">

I agree that it's risky to embed a password in the url, but I don't mind
embedding the username of the "Anonymous" user in the URL.  Unlike Andy, I
don't get prompted for authentication in IE.  I wonder what the difference
is.  I have tried with &USERNAME=Anonymous and with
&USERNAME=Anonymous&PASSWORD=  and neither prompts in IE, Opera, or Firefox.

thanks Andy, how are the OSMG demos working, I don't think I was prompted
when I viewed them?  Is there a walkthrough for using the .Net viewers from
another hosting page (like in the php example demos)

I was following the parameter discussions from yesterday, interesting
indeed. I'm not sure I like embedding user/pwd in urls though. 

cheers
brian

I don't think you're missing anything.  The only way I've seen to open a web
layout without user login prompt is to embed it in a web page.  In that
page, you have to programmatically create a session based on a valid user
and pass the session at the URL.  The example applications show this.

There was some discussion on GETMAP request parameters yesterday.  I just
tried adding &USERNAME=Anonymous to the URL.  In Internet Explorer, I still
get the user login dialog, but can just click on OK or Cancel without
entering anything and it opens fine.  With Firefox, I am not prompted for
login and the layout opens fine.

When I create a simple Map Layout and try to access it from a browser, I
always get the login screen. I thought if "Everyone" was assigned read
access to it, there would be no logon request. Again, I'm probably missing
the obvious...
