SolMan and Dev client

Hello!

We are in the configuration phase now using SM4.0. Our SolMan-Prod is connected to the Dev client (Golden client) as target. The team is configuring using solar02 and accessing the IMG and completing the configuration document. Some team members access the Dev client directly and complete the configuration, My question is,

How do I restrict access to the Dev client directly by the team members?

The team members should have access to the Dev-IMG thro' SolMan only and not directly. That way there is better control in the configuration phase.

Appreciate any inputs.

Thanks.
