I'm trying to get all users of a particular group in AD, then return a list of Employees as mapped to properties in my Employee class. I have:
My Filter is producing no results - what should it be?
Also, I tried the first solution here: List of users in specific Active Directory Distribution Group, but I need details such as mobile, extension, etc. which I couldn't get with that method.
public static List<Employee> CreateEmployeeList(string department)
{
List<Employee> employees = new List<Employee>();
string filter = string.Format("(&(ObjectClass=person)(memberOf=CN={0},OU=Users & Groups,OU=Blah,DC=Blah,DC=Blah,DC=Blah))", department);
DirectoryEntry adRoot = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
DirectorySearcher searcher = new DirectorySearcher(adRoot);
searcher.SearchScope = SearchScope.Subtree;
searcher.ReferralChasing = ReferralChasingOption.All;
searcher.Filter = filter;
SearchResultCollection results = searcher.FindAll();
foreach (SearchResult user in results)
{
// do whatever you need to do with the entry
if (user != null)
{
UserDirectoryEntry = user.GetDirectoryEntry();
string displayName = GetUserProperty("displayName");
string firstName = GetUserProperty("givenName");
string lastName = GetUserProperty("sn");
string email = GetUserProperty("mail");
string tel = GetUserProperty("telephonenumber");
string extension = GetUserProperty("ipphone");
string mobile = GetUserProperty("mobile");
string title = GetUserProperty("description");
employees.Add(new Employee{ FullName = displayName, FirstName = firstName, Surname = lastName, Email = email.ToLower(), Telephone = tel, Extension = extension, Mobile = mobile, JobTitle = title });
}
}
return employees;
}
using (var context = new PrincipalContext(ContextType.Domain, "domainName"))
{
using (var group = GroupPrincipal.FindByIdentity(context, "groupName"))
{
if (group == null)
{
MessageBox.Show("Group does not exist");
}
else
{
var users = group.GetMembers(true);
foreach (UserPrincipal user in users)
{
//user variable has the details about the user
}
}
}
}
