forms authentication with iis basic

[Freelve]

I've got an existing asp application. I'm going to start migrating it to<BR>asp.net. The current app is configured (and requires) iis to have basic<BR>authentication on the directories containing the asp code. My question is if<BR>I use forms authentication on the .net pieces, how can I pass the user<BR>information to iis so that the user isn't forced to go through the popup box<BR>sent by iis when the user goes to a resource protected by iis basic<BR>authenticaion. I don't think .net forms auth is getting iis to authenticate<BR>so iis is asking for the user information again. Is there a way for my .net<BR>forms auth code to create a security principal and pass it to iis and have<BR>that user authenticated through both basic auth (from iis) and forms auth<BR>(through .net).???????<BR><BR>The site runs over ssl so the clear text basic auth isn't an issue.<BR><BR>root - anonymous access - this is where my forms auth login is<BR>--appPages - basic auth - bulk of the asp pages<BR><BR>forms auth works fine but when I navigate to any of the dirs under appPages,<BR>basic auth kicks in and pops up the dialog requiring userid and password for<BR>iis - ie forms auth isn't telling iis who the user is<BR><BR>Thanks for any help...<BR>[email protected]
