Querying Active Directory
A while ago i wanted to figure out which demo accounts i had already created in my Active Directory. Since i was smart enough to give them all a description ‘Demo User’ this was easily done as following
using( DirectoryEntry directoryEntry = new DirectoryEntry() )
{
using( DirectorySearcher directorySearcher = new DirectorySearcher() )
{
directorySearcher.Filter = "(&(objectClass=user)(description=Demo User))";
directorySearcher.SearchScope = SearchScope.Subtree;
directorySearcher.Sort = new SortOption("displayname", SortDirection.Ascending );
SearchResultCollection results = directorySearcher.FindAll();
foreach( SearchResult result in results )
{
ResultPropertyCollection propertyCollection = result.Properties;
Console.WriteLine( "{0}: {1}", propertyCollection\["displayname"\]\[0\].ToString(), propertyCollection\["description"\]\[0\].ToString() );
}
}
}
