Here is a sample to do that by using extensibility call :
class DSPrincipals
{
static void Main(string[] args)
{
/* Retreiving a principal context
*/
PrincipalContext domainContextMonou = new PrincipalContext(ContextType.Domain, "WM2008R2ENT:389", "ou=Monou,dc=dom,dc=fr", "jpb", "pass@1w0rd01");
/* Create a user principal object
*/
slxUser aSlxUser = new slxUser(domainContextMonou, "W.Zeidan", "pass@1w0rd01", true);
/* assign some properties to the user principal
*/
aSlxUser.GivenName = "Wessam";
aSlxUser.Surname = "Zeidan";
aSlxUser.streetAddress = "Add1";
/* Force the user to change password at next logon
*/
aSlxUser.ExpirePasswordNow();
/* save the user to the directory
*/
aSlxUser.Save();
Console.ReadLine();
}
}
[DirectoryObjectClass("user")]
[DirectoryRdnPrefix("CN")]
class slxUser : UserPrincipal
{
public slxUser(PrincipalContext context)
: base(context) { }
public slxUser(PrincipalContext context, string samAccountName, string password, bool enabled ) : base(context, samAccountName, password, enabled)
{
}
[DirectoryProperty("streetAddress")]
public string streetAddress
{
get
{
object[] result = this.ExtensionGet("streetAddress");
if (result != null)
{
return (string)result[0];
}
else
{
return null;
}
}
set { this.ExtensionSet("streetAddress", value); }
}
}
You'll find more information in MSDN documentation.
Here is the result :
