Complex Security Model

[Anonymous]

Hello,

Im trying to achive a slightly more complex security model than just a single filter.

The idea is to filter the table named "Security" using RLS with USERPRINCIPLANAME() to filter that table.

The security levels are 1 to 4 with 1 being the highest and 4 the lowest.

So:

• If a user has a level of 1 on a project they should see all sources that are tagged 1, 2, 3, or 4 but also be locked to only the projects they can see.
• If a user is a 2 then they shouldnt be able to see any data that is tagged with a level on 1.

I have attached a link to an example file that works perfect for just the single project level filtering but I need to involve the security columns too.

Can anyone offer any advice on how this could be done?

Hi Chris_k, you could try to split up your security table in to parts, one  cointaining the project a user is entitled to see and one with the security level of the users for each project. 

In the security level table, create a new column which is a combination of project and security level, projectSecLvl. Create the same column in table 1 and table 2. Add many-to-many filters between security level table and table 1 and table 2, with filter direction from securityLevel to table1/table2.

Add filter in the manage role window on both security and securityLevel where email=userprincipalname().

It works with the simple example file you provided, but I have not tested it for larger data sets so not sure if that works. 

Your sample file does not contain any examples of the type security level 1 should see all other levels. A way to solve this could be to add all the levels for a user in the security level  table. E.g. if user1 has security level 1 = 1 on project X7, then add rows to the security level table for user 1 for project X7 level 2,3 and 4.
