> While syncing with LDAP, username collisions should be handled based on an 
> LDAP sync configuration value.
> The configuration options should be to indicate the following behaviors
> * convert 
> ** convert the existing (non-LDAP user) user to an LDAP user
> ** This is the existing behavior
> * skip
> ** skip or ignore the collision, leaving the existing user unchanged
> ** a new user record should not be created
> Note: Future behavior may be to cause the sync operation to fail, but that 
> shouldn't be handed yet.
> This configuration value should be set when setting up LDAP sync properties 
> via {{ambari-server setup-ldap}} and be enforced when processing the sync 
> operation in methods like 
> {{org.apache.ambari.server.controller.AmbariManagementControllerImpl#synchronizeLdapUsersAndGroups}}
>  or {{org.apache.ambari.server.security.authorization.Users#processLdapSync}}.
