connecting to Active Directory

Question

Hello.
Your help is very much appreciated.
I am trying to get the groups a specific user belongs to from Active Directory.
Iv'e see many examples of how to do it.
But, I don't understand one basic thing...
How to tell Active Directory, which user I want to get the groups for????

in the examples I see connections string like:

"LDAP://DC=Microsoft,DC=COM" "name" "Microsoft"

What is DC??????

My connection string:

DirectoryEntry x = new DirectoryEntry(LDAP://myservername,"username","password",System.DirectoryServices.AuthenticationTypes.ServerBind);

will get me connected to Active directory.
but how do I specify which user I want to enquire????
the user name and password used in the code above are for connecting to active directory...

Thanks
Roy

Some thing like this: string user = mike; //loging name to search for... DirectoryEntry adEntry = new DirectoryEntry(connectionString); DirectorySearcher adSearch = new DirectorySearcher(adEntry); adSearch.Filter = (cn= + user + ); //this is basicly your querystring... adSearch.PropertiesToLoad.Add(cn); adSearch.PropertiesToLoad.Add(mail); SearchResult result = adSearch.findOne(); result.Properties[cn][0].toString(); //Returns individuel records on the profile - in this case cn - Im not that sure on this command tho but some thing like that :) If you search for several users or in other ways would get more than one result back use: SearchResultCollection instead of SearchResult adSearch.FindAll() instead of adSearch.FindOne(); For the Groups... They are usually(if not always?) stored in a field called ou(Organization Units). Pull that data like and other fields - just remember that u get a array back with the data... adSearch.PropertiesToLoad.add(ou); ..... adSearch.Properties[ou][0]; adSearch.Properties[ou][1]; adSearch.Properties[ou][2]; All above code is just written from memory so dont exspect to be able to copy/paste it :) Good luck!
