Currently, Crowd creates a new User DN using the new user id string (same value as the sAMAccountName attribute)

Example for user John Smith:

CN=jsmith,OU=Users,DC=Domain,DC=com

However Active Directory uses the First Name concatenated to the Last Name, that in Crowd we parse as the displayName.

Example for user John Smith:

CN=John Smith,OU=Users,DC=Domain,DC=com

Currently, Crowd is not able to create User DNs in the same format that AD does
