writing posixAccount to LDAP doesn't work - asp.net-mvc-4

Question

I tried to write PosixAccount on LDAP to an existing user. i get no error, but when checking LDAP the new entry has not been written.
i added a new user first which is working well!
=>
public bool RegisterUser(UserObject userObj, HttpContext httpContext){
bool success = false;
//create a directory entry
using (DirectoryEntry de = new DirectoryEntry())
{
try
{
InitializeCommonDataForDirectoryEntry(
de,
String.Format("{0}/{1}",
GetConfigEntry(Common.CommonDefinitions.CE_LDAP_CONFIG_SERVER, httpContext),
GetConfigEntry(Common.CommonDefinitions.CE_LDAP_CONFIG_DIRECTORY_ENTRY_ROOT, httpContext)),
httpContext);
DirectorySearcher ds = new DirectorySearcher(de);
ds.SearchScope = System.DirectoryServices.SearchScope.Subtree;
ds.Filter = "(&(objectClass=organizationalUnit)(ou=people))";
SearchResult result = ds.FindOne();
if (result != null)
{
DirectoryEntry myDirectoryEntry = result.GetDirectoryEntry();
DirectoryEntry newEntry = myDirectoryEntry.Children.Add(String.Format("cn={0}", userObj.userName), "inetOrgPerson");
if (userObj.company != null && !userObj.company.Equals(String.Empty))
newEntry.Properties["businessCategory"].Add(String.Format("{0}", userObj.company));
newEntry.Properties["givenName"].Add(String.Format("{0}", userObj.firstName));
newEntry.Properties["sn"].Add(String.Format("{0}", userObj.lastName));
newEntry.Properties["uid"].Add(String.Format("{0}", userObj.userName));
newEntry.Properties["mail"].Add(String.Format("{0}", userObj.email));
userObj.password = GenerateSaltedSHA1(userObj.password);
newEntry.Properties["userPassword"].Add(String.Format("{0}", userObj.password));
newEntry.Properties["pager"].Add(String.Format("{0}", userObj.newsletter));
newEntry.Properties["initials"].Add(String.Format("{0}", GetConfigEntry(Common.CommonDefinitions.CE_MOWEE_PACKAGE_1, httpContext)));
newEntry.CommitChanges();
newEntry.RefreshCache();
success = true;
}
}
catch (Exception ex)
{
Trace.Write("Exception : RegisterUser: " + ex);
GeneralUtils.SendBugMail(ex, httpContext);
}
}
return success;
}
after that i want to write posixAccount for that user, which is not working
maybe someone can help me PLEASE and check what i did wrong !?

I think the error you get would be informative for diagnosing any further.
When you create an object in AD I am pretty sure even if you do not specify a CN you get a default naming attribute of CN set. So this posixAccount create, which is setting cn, might be conflicting with an existing cn value. I forget if CN is multivalued or single valued in AD, but if it is single valued this would make more sense.
