[Mono-list] AuthenticationTypes.Secure problem

[Wallmander Jonathan]

Hello,

I'm trying to write a small script that verifies users against AD using =
mono.
Or rather, I'm porting one from windows.NET and want to run this in mono =
on linux.

Here's the code, based on examples here:

			DirectoryEntry de =3D new =
DirectoryEntry("LDAP://server.domain.net/DC=3Dfoo,DC=3Dbar,DC=3Dbaz,DC=3D=
net"
				,"myusername\myusername","mypass",AuthenticationTypes.Secure);
			DirectorySearcher src =3D new =
DirectorySearcher("(objectclass=3DUser)");
			//DataTable for users
			DataTable tbUsers =3D new DataTable("users");
			//Create Columns for DataTable.
			tbUsers.Columns.Add("cn",System.Type.GetType("System.String"));
			ds.Tables.Add(tbUsers);
			//DataTable for properties
			DataTable tbProperties =3D new DataTable("properties");
			//Create Columns for DataTable.
			=
tbProperties.Columns.Add("PropertyName",System.Type.GetType("System.Strin=
g"));
			=
tbProperties.Columns.Add("PropertyValue",System.Type.GetType("System.Stri=
ng"));
			ds.Tables.Add(tbProperties);
				=09
			src.SearchRoot =3D de;
			src.SearchScope =3D SearchScope.Subtree;
			src.Filter =3D ("(SAMAccountName=3Dmyusername)");
			SearchResult res =3D null;
			{
				res =3D src.FindOne();
				Console.WriteLine(res.ToString());
			}
		=09
			/*catch (Exception ex) {
				Console.WriteLine("Error authenticating user." + ex.Message);
			}*/
		=09
			//foreach(SearchResult res in src.FindAll())
			//{
				//System.Collections.IDictionaryEnumerator ien =3D =
res.Properties.GetEnumerator();
			if (res !=3D null) {
				DataRow topRow =3D ds.Tables["users"].NewRow();
				topRow["cn"] =3Dres.Properties["cn"][0];
				ds.Tables["users"].Rows.Add(topRow);
				DataGrid1.DataSource =3D ds.Tables["users"];
				DataGrid1.DataBind();
			}

---------


On the linux server (apache+mod_mono), i get this error:

Error Message: HTTP 500.

The examples

Does this mean that the .Secure type of the AuthenticationTypes enum =
isn't available? From what I can see,
AD uses kerberos+LDAP (but the manual of the .Secure in msdn says NTLM)
and hence should be possible to implement in mono on linux.. Or am I =
wrong?

Any explanation about this or help greatly appreciated :)
