Hi everybody.

In advance sorry if my questions are "stupid" but I'm beginner in the DNN World and, after some researchs, I need help for the following subject.

I have installed DNN 4.5.1 and the portal is up. Now I would like to enable windows authentication AND local authentication.

mixed mode = The possibility to allow authentication from LDAP server AND from local database user. Correct ?

If yes,I would like activate "mixed mode" authentication on my portal.Then, my first question is : what's the correct and comlete definition in the web.config file for activate "Mixed mode" ?

The server where the DNN portal is installed isn't member of the domain (because the server is in DMZ).

Then my second question is : may do that ?

Thank you in advance for your responses

I'm trying to follow the instructions in the suggested post, but I'm turning around.

In the post suggested above, the first step is "Admin settings" (the DNN configuration for windows authentication).

Then I apply (I hope) all the suggested settings ad I receive the following response :

Error: Windows Authentication is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Security.Authentication.ADSI.Utilities.AddADSIPath(String Path, Path ADSIPath) at DotNetNuke.Security.Authentication.ADSI.Utilities.GetRootEntry(Path ADSIPath) at DotNetNuke.Security.Authentication.ADSI.Utilities.GetRootEntry() at DotNetNuke.Security.Authentication.ADSIProvider.GetNetworkStatus() at DotNetNuke.Security.Authentication.AuthenticationController.NetworkStatus() at DotNetNuke.Modules.Authentication.AuthenticationSettings.cmdAuthenticationUpdate_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

Then I understand that I need to active "mixed mode" in the web.config file as following :

Before change :
<!-- Forms or Windows authentication -->
       <authentication mode="Forms">
       <forms name=".DOTNETNUKE" protection="All" timeout="60" cookieless="UseCookies" />
       </authentication>
<!--     
       <identity impersonate="true"/> 
      <authentication mode="Windows">
      </authentication>
-->

After change (if my understanding of the configuration for mixed mode is correct)
<!-- Forms or Windows authentication -->
       <authentication mode="Forms">
       <forms name=".DOTNETNUKE" protection="All" timeout="60" cookieless="UseCookies" />
       </authentication>
       <identity impersonate="true"/> 
<!--     
      <authentication mode="Windows">
      </authentication>
-->

In this case, I'm note able to acces the portal :

DotNetNuke Error: - Version 04.05.01

User does not have permission to perform this action.

FYI, My server is actually in the domain, for an easyer environment.

Have you any suggestion for me ?

Thank you  in advance

You may not have to uncomment the <identity impersonate="true" /> but if you do you'll probably have to add a userName="domain\username" password="password" to it (<identity impersonate="true" userName="somedomain\mikeh" password="password" />. There are some other changes that need to be done but first see if the connection works.
