searching what groups a user belong from AD but errorThe Kerberos subsystem encountered an error. A service for user protocol request was made
I want users to be able to type a user name in a textox and when they hit
submit displays groups the user belongs to from the Acive Directory. the getGroupforUser uses the WindowsIdentity and i have a button even below. In the button event below i just want to send the username typed in in the textbox but when i test the page i get error :- "System.Security.SecurityException: The Kerberos subsystem encountered an error. A service for user protocol request was made against a domain controller which does not support service for user." Any ideas?? List<string> getGroupsforUser(WindowsIdentity id) { List<string> groups = new List<string>(); IdentityReferenceCollection irc = id.Groups; foreach (IdentityReference ir in irc) { NTAccount acc = (NTAccount)ir.Translate(typeof(NTAccount)); groups.Add(acc.Value); } return groups; } ----------------------------------------------------------------------------------- protected void LookupADBtn_Click(object sender, EventArgs e) { string username = aduser.Text; Response.Write("You are logged in as " + username + " your GROUPS are: "); //WindowsIdentity id = (WindowsIdentity)HttpContext.Current.User.Identity ; WindowsIdentity id = new WindowsIdentity(username); foreach (string roles in getGroupsforUser(id)) { Label1.Text += "<br>" + roles.ToString(); } } |
Re: searching what groups a user belong from AD but errorThe Kerberos subsystem encountered an error. A service for user protocol request was made
The error is exactly what you it says it is. The constructor you are using
on the WindowsIdentity object uses Kerberos protocol transition (S4U or service for user) in order to generate the user's token. This function requires that the client is 2003 or higher and that the domain controller servicing the request is 2003 AD in 2003 forest functional level. Apparently, it is not. If you don't know for sure that your DCs are converted over, you can't safely use this feature. The code you have commented out would probably work fine though if your application was using Windows security in IIS (basic, digest or IWA). Why not just use that?

Re: searching what groups a user belong from AD but errorThe Kerberos subsystem encountered an error. A service for user protocol request was made
Thanks very much Joe for ther prompt reply
The DC is still in W2k windows 2000 server..arg..... Are u talkng about this line below WindowsIdentity id = (WindowsIdentity)HttpContext.Current.User.Identity ; It does work when i use that but i want users to type in a username and hit the button to search other users.. Can i use DirectoryServices fr this sceanrio..

Re: searching what groups a user belong from AD but errorThe Kerberos subsystem encountered an error. A service for user protocol request was made
Yeah, you would need to do an LDAP lookup for the user's groups using
tokenGroups to simulate what the protocol transition logon is doing. Or, get the admin to upgrade the DC. :) Joe K. -- Joe Kaplan-MS MVP Directory Services Programming Co-author of "The .NET Developer's Guide to Directory Services Programming" http://www.directoryprogramming.net -- "rote" <naijacoder@hotmail.com> wrote in message news:u335DBFSIHA.5264@TK2MSFTNGP02.phx.gbl... > Thanks very much Joe for ther prompt reply > The DC is still in W2k windows 2000 server..arg..... > Are u talkng about this line below > WindowsIdentity id = (WindowsIdentity)HttpContext.Current.User.Identity ; > It does work when i use that but i want users to type in a username and > hit the button to search other users.. > > Can i use DirectoryServices fr this sceanrio.. > Thanks in advacne once again > > > > "Joe Kaplan" <joseph.e.kaplan@removethis.accenture.com> wrote in message > news:ufR$TaESIHA.1208@TK2MSFTNGP05.phx.gbl... >> The error is exactly what you it says it is.

Joe the admin won't update it because they are damn too lazy.
I'm trying yo use this code here as a guide but its returning null when passing a search result : http://www.wwwcoder.com/main/parenti...8/default.aspx Any ideas.. Do you have a sample snipprt using tokenGroups somehwere on your site been trying to find a guide from there but to success. Thanks in advance..

Joe are you talking about this snippet code below ?
Is it this one? On the line "foreach (byte[] sid in user.Properties["tokenGroups"]) whats the user? Is it the DirectoryEntry object. The code doesn;t look complete or something..

Re: searching what groups a user belong from AD but errorThe Kerberos subsystem encountered an error. A service for user protocol request was made
Joe i have modified the code and i can get the TokenGroups based on a user..
But no groups are displayed .. But i can see the filter query like so:- (|(objectSid=0x01 0x02 0x00 0x00 0x00 0x00 0x00 0x05 0x20 0x00 0x00 0x00 0x21 0x02 0x00 0x00 )(objectSid=0x01 0x02 0x00 0x00 0x00 0x00 0x00 0x05 0x20 0x00 0x00 0x00 0x20 0x02 0x00 0x00 ) and also see how many tokengroups are returned..

That query filter does not look right. The SIDs should look like:
\xx\xx\xx\xx\xx I can't see how your call to BuildFilterOctetString produced the output that you got. Are you sure you called it right?

Re: searching what groups a user belong from AD but errorThe Kerberos subsystem encountered an error. A service for user protocol request was made
I was just about to write back Joe.
I was using :- private string BuildFilterOctetString(byte[] bytes) { StringBuilder sb = new StringBuilder(); for (int i = 0; i < bytes.Length; i++) { sb.AppendFormat("0x{0} ", bytes[i].ToString("X2")); } return sb.ToString(); } Instead of private string BuildFilterOctetString(byte[] bytes) { StringBuilder sb = new StringBuilder(); for(int i=0; i < bytes.Length; i++) { sb.AppendFormat( "\\{0}", bytes[i].ToString("X2") ); } return sb.ToString(); } After i changed that it worked like a charm.And by the way congrats on your new born baby. One more question is can i do group names to return me users that belongs to those groups?
