Active Direcetory link for F5 Management

Hi,

 

I'm having troubles to authenticate users on F5 through Active Directory. The scenario shows like:

 

1. Bind correctly with AD, the user has vision and acces to all the three, then checked the option no access, to create remote groups.
2. Crear Remote Groups, if i create a remote group mapping a group (CN=GroupX) it works, using MemberOF attribute.

The problem comes when I try to map inside a Remote Group and entire OU, obviously the MemeberOf attribute doesn't work, any suggestion? It's possbile to map and OU without CN?

 

I double checked the guides but doens't found anything with this,
