Constraint Violation Problem

How can I check the manager property using the distinguishedName for updating?

I am trying to update the manager property in Active Directory using data from a database. I need to check if the manager name from the db is the same as in Active Directory, if the name is not the same don't do nothing. If the name is the same update the name for the manager.

I found this code over the Internet but I don't understand it. I what the guy refers to with dc1.ad.... + dnOfManager. I know what the domain is but not the rest. Any help will be very appreciated.

Code:

---

if(DirectoryEntry.Exists("LDAP://dc1.ad.domain.com/" + dnOfManager))
{
// update user object with dnOfManager
}
else
{
// manager object does not exist
}

This is what I am trying:
                try {
                  string supervisor = "";
                  string lastName = "";
                  string firstName = "";
                  string mngr = "";

                  supervisor = oEmployee.Manager;

                  if (supervisor.Contains(",")) {
                    string[] split = supervisor.Split(new Char[] { ',' });
                    lastName = split[0];
                    firstName = split[1];
                    mngr = "CN=" + lastName + @"\," + firstName + ",CN=Users,DC=domain,DC=net";
                  }
                  if (DirectoryEntry.Exists("LDAP://" + "CN=" + lastName + @"\, " +
                      firstName + "," + "CN=users,DC=domain,DC=net")) {
                    if (supervisor != String.Empty) {
                      dentry.Properties["manager"].Value = mngr;
                    }
                  }
                  else {
                 
                    Console.WriteLine("Could not update Manager Property in Active Directory.");
                    if (flE.Exists) {
                      using (sw = flE.AppendText()) {
                        sw.WriteLine("===========================");
                        sw.WriteLine(DateTime.Now.ToShortDateString() +
                              " " + DateTime.Now.ToShortTimeString());
                        sw.WriteLine("Could not update Manager for: " + oEmployee.EmpFullName + " : " + oEmployee.empId);
                        sw.WriteLine(" ");
                        sw.WriteLine("===========================");
                      }
                    }
                  }
                }
                catch (Exception e) {
                  if (flE.Exists) {
                    using (sw = flE.AppendText()) {
                      sw.WriteLine("===========================");
                      sw.WriteLine(DateTime.Now.ToShortDateString() +
                            " " + DateTime.Now.ToShortTimeString());
                      sw.WriteLine("Error: " + e.Message);
                      sw.WriteLine("Trying to update the Manager Property in Active Directory.");
                      sw.WriteLine("EmployeeID: " + oEmployee.empId);
                      sw.WriteLine(" ");
                      sw.WriteLine("===========================");
                    }
                  }
                }

Did you read the FAQs (frequently asked questions) especially the one titled "BEFORE you post"???

They are also codered in my signature (but it looks like you didnt set up your profile to enable private messaging - so issues like this do not clutter the thread, and probably did not enable the viewing of signatures.

Also a search on "Code Tags" would have turned up samples...

They are the like the following but without spaces inside the brackets
