This application enforces security several ways, including permissions, authentication, and security policies. Setting and viewing access to various features occurs in the Control Panel of the Web client. Essentially, you can create user groups, and assign permissions to them.
Functional permissions originate with user groups, and are application-wide. See the Redcell Synergy User Guide for additional information.
When trying to restrict user access to particular functions, create a user group (see the Redcell Synergy User Guide), and assign the desired functional permissions to that group, then assign users to that group.
