Combining User Security Identifiers and Group Security Identifiers in Security Filters - V5.3 Onwards

Security Identifiers are used by Security Filters

It is possible to combine both User Security Identifiers with Group Security Identifiers to create more complex Security Filters for a user. In this scenario a logical AND will be applied between User and Group Security Filters when the filter is applied to a dataset:

1. In user admin, create a User Security Identifier for a user.
2. In groups admin, create a Group Security Identifier for a group.
3. In User admin, tick that you would like to apply both User Security Identifiers AND Group Security Identifiers when creating a Security Filter for the user.
    
4. In theory it is possible to have all five options here ticked, but rarely would you need to apply all five security filters.
