Jiri,
I do have an open case with SolarWinds. I'll keep this post updated with progress.
- We have a custom property that allows us to select a specific department. That is how we are managing the groups. If a device is tagged with "Network" there is a dynamic query to include them in a "Network" group. Then the users are limited by that group.
- They are not flat. For the server and middle tier teams they have nested "groups" by application. I.E. Oracle / Peoplesoft / etc.
- We haven't added any any new groups post upgrade, Do you know what changes that were made related to limitations? I can't seem to find it in the white papers.
**Update** We flattened a group and the issue still persists. In addition, if a group of group limitation is applied users can not see a node summary page either.
