IIS Express Windows Authentication

Question

I m trying to use IIS Express with VS2010 to host a silverlight application   I modified my applicationhost config file to allow for modification of the proper configuration settings   I have the following in my web config    lt location path    gt     lt system webServer gt       lt security gt         lt authentication gt           lt anonymousAuthentication enabled  false    gt           lt windowsAuthentication enabled  true    gt         lt  authentication gt       lt  security gt     lt  system webServer gt   lt  location gt    I am not being authenticated and my domain service call returns a null record as the user   I was able to get this to work after installing VS2010 SP1 BETA but I m trying to get this to work with only IIS Express   How do I enable Windows Authentication to work with IIS Express   Is there a configuration setting that I am missing

In addition to these great answers  in the context of an IISExpress dev environment  and in order to thwart the infamous  system web identity impersonate  error  you can simply ensure the following setting is in place in your applicationhost config file    lt configuration gt       lt system webServer gt           lt validation validateIntegratedModeConfiguration  false    gt       lt  system webServer gt   lt  configuration gt    This will allow you more flexibility during development and testing  though be sure you understand the implications of using this setting in a production environment before doing so   Helpful Posts    http   forums iis net post 1873372 aspx http   www iis net learn application-frameworks building-and-running-aspnet-applications aspnet-20-breaking-changes-on-iis

Visual Studio 2010 SP1 and 2012 added support for IIS Express eliminating the need to edit angle brackets    If you haven t already  right-click a web-flavored project and select  Use IIS Express       Once complete  select the web project and press F4 to focus the Properties panel   Set the  Windows Authentication  property to Enabled  and the  Anonymous Authentication  property to Disabled      I believe this solution is superior to the vikomall s options     Option  1 is a global change for all IIS Express sites  Option  2 leaves development cruft in the web config     Further  it will probably lead to an error when deployed to IIS 7 5 unless you follow the  unlock  procedure on your IIS server s applicationHost config      The UI-based solution above uses site-specific location elements in IIS Express s applicationHost config leaving the app untouched   More information here  http   msdn microsoft com en-us magazine hh288080 aspx

In IIS Manager click on your site  You need to be  in feature view   rather than  content view    In the IIS section of  feature view  choose the so-called feature  authentication  and doulbe click it  Here you can enable Windows Authentication  This is also possible  by i think in one of the suggestions in the thread  by a setting in the web config           But maybe you have a web config you do not want to scrue too much around with  Then this thread wouldnt be too much help  which is why i added this answer

On the same note - VS 2015   vs config applicationhost config not visible or not available  By default  vs folder is hidden  at least in my case   If you are not able to find the  vs folder  follow the below steps   Right click on the Solution folder select  Properties  In Attributes section  click Hidden check box default unchecked   then click the  Apply  button It will show up confirmation window  Apply changes to this folder  subfolder and files  option selected  hit  Ok    Repeat step 1 to 5  except on step 3     this time you need to uncheck the  Hidden  option that you checked previously   Now should be able to see  vs folder

Building upon the answer from booij boy  check if you checked the  windows authentication  feature in  Control Panel -  Programs -  Turn windows features on or of -  Internet Information Services -  World Wide Web Services -  Security  Also  there seems to be a big difference when using firefox or internet explorer   After enabeling the  windows authentication  it works for me but only in IE
