Known Security System module scenarios unsupported out of the box

Uncovered Security System scenarios fall into two categories:
1.  Scenarios where we can simplify solutions.
How to add a custom persistent field via the Application Model XAFML stored in DB when the middle-tier Application Server is used

2.  Scenarios that cannot be implemented using the current architecture:
Duplicate records can be created when using SecuredObjectSpaceProvider or a middle-tier application server despite RuleUniqueValue, RuleObjectExists and other validation rules

Most of these scenarios are quite rare and specific. Though it is possible that most of you will not face them in your real apps, we still think that it is worth mentioning them here. These enhancements are a subject for further discussion and we cannot provide any ETA for them. We will keep updating this document as we reveal new scenarios. Do not hesitate to contact our Support Team if you have any questions on the subject.

In addition, please refer to the Security - How to reduce the number of permission requests and improve overall performance KB Article for the full list of possible technical solutions for security module performance tuning in various configurations.

    Thanks for your feedback on the cached service, Carlos. Would you please elaborate a bit more on the reasons for "Dropped it and am using the web client now"?

      The win client is super slow because of the generated sql queries over the vpn. You can look at: https://www.devexpress.com/Support/Center/Question/Details/T214347
      So i changed to the web client and performance wise it's much faster for users as the web client generates gazillions of queries but the db server is next to it in the same subnet. In contrast, the win client generates the gazillion queries but these need to be sent over the VPN causing horrible performance for the client. Users are happy with the change (from win to web). Not sure however if the app will scale as there will be more office to start using the web application. But we'll see.
