Re: [ADVANCED-DOTNET] Serialization Problem
Thomas is right,
first of all check if the bug is in the serialization or in the transission.
You can see this: try to deserialize your object just after you have
serialized it (in the 'client') and before sending it. This will help to
localize the bug.
To give you an idea, the code follow.
HTH (luKa)
http://nullabletypes.sourceforge.net/
[nu.Test]
public void SerializationTest() {
NullableInt32 serializedDeserialized;
serializedDeserialized = SerializeDeserialize(_null);
nua.Assert("TestA#01", _null.Equals(serializedDeserialized));
}
private NullableInt32 SerializeDeserialize(NullableInt32 x) {
System.Runtime.Serialization.Formatters.Soap.SoapFormatter serializer =
new System.Runtime.Serialization.Formatters.Soap.SoapFormatter();
using (sys.IO.MemoryStream stream = new sys.IO.MemoryStream()) {
serializer.Serialize(stream, x);
sys.Text.Decoder d = sys.Text.Encoding.Default.GetDecoder();
stream.Seek(0, sys.IO.SeekOrigin.Begin); // Return stream to start
NullableInt32 y = (NullableInt32)serializer.Deserialize(stream);
stream.Close();
return y;
}

[ADVANCED-DOTNET] DirectoryServices / Security issue?
I've an ASP.NET web server that impersonate's its clients. The web server tries to lookup an Active Directory property via DirectoryServices.DirectorySearch. The machine that the web server runs on is configured in Active Directory to allow credential delegation. I am looking for a certain user, and am searching by "sAMAccountName=XXX". When I run the web server on localhost (with browser client also on the same machine), I can find 'XXX' just find via DirectorySearcher.FindOne, and examine the property I'm interested in. For some reason, when I move my browser client to another machine, the DirectorySearcher.FindOne method returns null. I know the Directory entries are there. If I start a cmd prompt on the other machine and run the W2K LDP.EXE utility, I see the user and the properties I want. The LDAP / Active Directory server is the same -- just a pretty vanilla W2K Active Directory (*non* mixed mode). I've tried playing around with DirectoryEntry.AuthenticationType, setting it to Secure, as well as trying Secure | ServerBind | ReadonlyServer. No go -- still nothing found. I have confirmed in the debugger that the Thread Principal Identity is the browser client identity. I've tried clients as W2K3 Servers (actually a Terminal Services client onto a W2K3 Server, where the TS client is an XP box) as well as XP machines (no Terminal Services -- just straight connection to the web server). Is there some limitation between Impersonation and DirectoryServices?

Re: [ADVANCED-DOTNET] Serialization Problem
Before you deserialize, try dumping the information you receive to a trace log. In all cases where I have seen this, I have been receiving an error message of some kind instead of the serialized object. Then when the BinaryFormatter tries to deserialize the object, it incorrectly mistakes some text or corrupted data as a version number.

[ADVANCED-DOTNET] Security Question: SSPI to validate user?
Is there a simple way to validate a user (e.g username and password) without getting a token back using SSPI? I know I can call the LogonUser API, but I just need to find out if the credentials are valid? Am I on the right track with SSPI? === This list is hosted by DevelopMentor® http://www.develop.com >>> Error in line 16 of ADVANCED-DOTNET.MAILTPL: unknown formatting command <<< -> .NET courses you may be interested in: <-

If it works from one computer and not another, the first thing I would look at is if both are successfully authenticating with Kerberos authentication instead of NTLM. To access the AD as the impersonated user, the web server requires full network credentials. This can be supplied by basic auth, as both username and password are present, or by kerberos which will auththenticate behind the scenes using tokens. I would download Kerbtray from microsoft and compare your tickets. I have had some situations where we could not get kerberos to work, even though the environments seem the same. In some cases wiping out the users profile and starting over solved the problem, but that's not a very satisfying solution. === This list is hosted by DevelopMentor® http://www.develop.com >>> Error in line 16 of ADVANCED-DOTNET.MAILTPL: unknown formatting command <<< -> .NET courses you may be interested in: <-
Re: [ADVANCED-DOTNET] DirectoryServices / Security issue?
It may be a CodeAccessSecurity issue. When you run as local host, you're in a different zone that on the other machine probably...but I would have expected a security error, not a NULL, but thought I'd throw a hint out in case.

[ADVANCED-DOTNET] System.Reflection.EventInfo.GetRaiseMethod always returns null?
Using .NET 1.1 and C#, has anyone written code that successfully retrieves the MethodInfo from the EventInfo.GetRaiseMethod call? My type does includes a event declaration and ildasm reports it is a private field. The type retrieves the EventInfo and I can discover the Add/Remove methods correctly, but I always get null from the GetRaiseMethod(void or true or false). Also, no exception is ever throw. Any help is appreciated.
