The Trust Relationship Between The Primary Domain And The Trusted Domain Failed

Aug 3, 2010

We have a ASP.NET site that partially depends on forms authentication for login credentials, however the implementation of IPrincipal is completely custom.

But, when running the site on a particular server (which is somewhat semi-hardened when it comes to security), the app crashes when invoking IPrincipal.IsInRole() with the following messsage:

System.SystemException: The trust relationship between the primary domain and the trusted domain failed.

This indicates a communication error between the web-server and the DC, however since our application doesn't at all utilizes Windows authentication, I don't see why it needs to communicate with the DC.

This is my implementation:



I was finally enable to reproduce this error on my dev-machine (i revoked my machine from the DC yesterday, but didn't reproduce it until today)

HttpContext.User is actually a WindowsPrincipal by default it seems, and the error in my code was that I only replace it with CustomPrincipal upon login. Hence, unathenticated users still get the WindowsPrincipal which then fails horribly if you have trust issues on your AD.

I tried changing the default principal by invoking this on appstart

AppDomain.CurrentDomain.SetPrincipalPolicy( PrincipalPolicy.NoPrincipal);

But this doesn't seem to kick in. How do I change the default Principal in ASP.NET?

C# - PrincipalContext.ValidateCredentials Slow With Trusted Domain Using NetBios Name

Feb 18, 2011

I've created a service that validates credentials against Active Directory using System.DirectoryServices.AccountManagement. I need to validate credentials against the local domain as well as a trusted domain. The response time for validating credentials is fast for both the local and trusted domain when run on my computer. When I move this service to our server, the local domain response is fast however, the trusted domain response is very slow (20 - 30 seconds).

I've also found that if I change the domain name in the PrincipalContext from the NetBios name to the DNS name it corrects the the performance problem on the server.

Here's some examples

PrincipalContext context = new PrincipalContext(ContextType.Domain, sNetBiosName)
context.ValidateCredentials(sUsername, sPassword)

On the server, the above will take 20-30 seconds using the NetBios Name

PrincipalContext context = new PrincipalContext(ContextType.Domain, sDNSName)
context.ValidateCredentials(sUsername, sPassword)

Using the DNS name the response is 0-2 seconds

Any ideas on what needs to be setup on the server to speed this up using the NetBios name?

Security :: How To Set IIS To Handle Both Domain And Non-domain Users

Jan 27, 2011

I have an intranet web application. There are 2 user groups, group A belongs to the domain and group B does not. If I set the IIS to enable anonymous access, Request.ServerVariables("LOGON_USER") always return nothing. If I disable anonymous access and set Integrated Windows authenication, a Windows login prompt will come up if group B's users want to access the website.

How can I setup IIS so that when domain user access the website, it will direct to the main page with Session("user_name") = Request.ServerVariables("LOGON_USER"). If a user is not a domain user, the website will direct him/her to a login.aspx instead of having the Windows authenication prompt, then set Session("user_name") = txtUserName.Text, and finally redirect to the website main page ?

C# - Share Session Between Domain And Sub-domain?

May 4, 2010

We're doing a whitelabelled version of our site, which will be hosted at

However we need to ensure session is maintained between and, as our SSL certificate only covers the main domain.

In practice this means we'll swap to the main domain on our payment pages, which run HTTPS, and then redirect back to the subdomain, after payment.

So the question is: How do we maintain the session when doing so ?

I've tried with <httpCookies domain="" /> in web.config to no avail :-(

Edit: Figured it out now, I lacked domain on my <forms /> tag to handle login properly.

C# - Get Local Groups And Not The Primary Groups For A Domain User

Dec 18, 2010

i have a code to get the groups a user belongs to.

DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName));
DirectoryEntry user = adRoot.Children.Find(completeUserName, "User");
object obGroups = user.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
// Create object for each group.
DirectoryEntry obGpEntry = new DirectoryEntry(ob);
return true;
catch (Exception ex)
new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex);
return false;

the above code works fine when i have to find the groups of a local user but

for a domain user it returns a value "Domain User" which is kind of wierd as it is a part of 2 local groups.


I did some finding and got that i am being returned the primary group of the domain user

called "Domain User" group

but what i actually want is the groups of the local machines the domain user is a part of... i cannot get that.. any suggestions

another code using LDAP

string domain = Environment.UserDomainName;
DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
DirectorySearcher search = new DirectorySearcher();
search.SearchRoot = DE;
search.Filter = "(SAMAccountName=" + completeUserName + ")"; //Searches active directory for the login name
search.PropertiesToLoad.Add("displayName"); // Once found, get a list of Groups
SearchResult result = search.FindOne(); // Grab the records and assign them to result
if (result != null)
DirectoryEntry theUser = result.GetDirectoryEntry();
theUser.RefreshCache(new string[] { "tokenGroups" });
foreach (byte[] resultBytes in theUser.Properties["tokenGroups"])
System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0);
DirectorySearcher sidSearcher = new DirectorySearcher();
sidSearcher.SearchRoot = DE;
sidSearcher.Filter = "(objectSid=" + mySID.Value + ")";
SearchResult sidResult = sidSearcher.FindOne();
if (sidResult != null)
new GUIUtility().LogMessageToFile("no user found");
return true;
catch (Exception ex)
new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user.
return false;

this works too but i get the same result "Domain Users" . Please can some1 tell me how to get the local machine groups...?

<forms loginUrl="~Login.aspx" defaultUrl="Default.aspx" protection="All" timeout="80" name=".ASPXAuth" domain=""/>
but this thing just dosent work on the 1.1 application and throws an error Unrecognized attribute 'domain'.

C# - WebException Could Not Establish Trust Relationship For The SSL/TLS Secure Channel

Dec 20, 2010

My company has developed a .NET web service and a client dll that uses that web service. The webservice is hosted on our server over ssl and the cert is provided and signed by GoDaddy. We have some clients in a hosted environment that are getting the following error message from the client dll when it tries to access our web service.

System.Net.WebException The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Our fix has been to have them open IE on the server, which is a challenge in and of itself for a lot of the hosted services, and go to the WSDL url. IE then prompts them with a security alert dialog. It says the cert date is valid and a valid name matching the name of the page, but was issued by a company you have not chosen to trust. When they click Yes to proceed, the client dll can then succesfully connect to the web service and operate as normal. why GoDaddy would not have been in there valid publishers list? All of the servers we have running has GoDaddy as a valid authority. I'm guessing, for security reasons, they've uninstalled the authority for GoDaddy, but not totally convinced that there's not some other underlying issue.

Unfortunately, I haven't had much luck trying to recreate this locally. If I go into Internet Options and remove the GoDaddy authorities and hit our service, ssl works just fine. I go back into the list of publishers and GoDaddy gets put right back in. So my second question is, How the heck do you get rid of GoDaddy so I can get an invalid cert warning?

Okay, last question. Is there a way in code I can tell the web service to ignore invalid certs. I've seen some posts on doing this programatically with WCF but not old web services.
