FIM 2010 R2 Lotus Domino MA error

Hi,

I'm currently setting up a lab environment with the following configuration:

• a FIM 2010 R2 single server (with FIM Sync and FIM service)
• a Lotus Domino 8.5 server with customized LDAP schema
• Installed Domino Lotus 8.x connector to FIM (http://www.microsoft.com/en-hk/download/details.aspx?id=29038) in FIM server
• Installed Lotus Domino Client 8.5 FP3

I have tried to create a Management Agent (step 2 Connectivity) to Lotus Domino and I got the following error on event log:
 "Microsoft.MetadirectoryServices.ExtensibleExtensionException ---> System.NullReferenceException: Object reference not set to an instance of an object. 
   at Microsoft.IdentityManagement.MA.LotusDomino.NotesClientWrapper.DominoConfig.GetOrganizationalUnit(KeyedCollection`2 configParameters)

Forefront Identity Manager 4.1.3419.0" 

I would like to know if there is any problem during I create the Management Agent?
