Where is the domain name in a UserPrincipal object?

Question

I\'m using the System.DirectoryServices.ActiveDirectory classes to find all Active Directory users. The code is very simple:

var context = new P

For AD DS, the value of msDS-PrincipalName is the NetBIOS domain name, followed by a backslash ("\").

You can find it using :

/* Retreiving the root domain attributes
 */ 
sFromWhere = "LDAP://DC_DNS_NAME:389/dc=dom,dc=fr"; 
DirectoryEntry deBase = new DirectoryEntry(sFromWhere, "AdminLogin", "PWD"); 

DirectorySearcher dsLookForDomain = new DirectorySearcher(deBase); 
dsLookForDomain.Filter = "(objectClass=*)"; 
dsLookForDomain.SearchScope = SearchScope.base; 
dsLookForDomain.PropertiesToLoad.Add("msDS-PrincipalName"); 

SearchResult srcDomains = dsLookForDomain.FindOne();
