is there a current, or proposed, user security model for open gamma. I am thinking of an example where traders/managers on a trading desk can only see the trades booked to their desk’s portfolio or sub-portfolio.
Yes, it’s something we’re actively working on right now. It’s a role-based permissions system at the portfolio level combined with the use of a capabilities based security model to protect position and security level information. It won’t make the next release (due in the next week or so) but should in a release in the next 8-12 weeks.
are you planning any link to external authentication systems like active directory, or will it be only within the application?
We will support authentication against external systems. In the first instance you will be able to implement an interface to do any custom authentication, and in time we will have standard implementations for common external authentication systems.
