Synchronize Tivoli Directory Server via LDAP Proxy

Hello, 

I try to fix some issues in my environnement to be able to use an LDAP Proxy( Tivoli Directory Integrator)  to connect FIM 2010 R2  and Tivoli Directory Server. 

I created the Management Agent (IBM Direcotry Server) and check the container that i want to synchronize but when i run a first Full Import Profile to get the containers in the connector space , i have an error "Dropped-connection"

Any idea to resolve that !!!
