Need to add this abbreviated matrix (only the options in green) to the documentation: https://redhatmbu.aha.io/epics/SAT-E-452
The docs should also refer to a KCS article (forthcoming) that goes into the specific support tiers of all supported, tested, or unsupported IdM methods.
The docs should also remove any information about non-Tier 1 (aka supported) authentication methods. The full support matrix is here: https://docs.google.com/spreadsheets/d/1QSVwnjPPoTbDNMVm6dGzDE0gNfPoLrBFsAwXgVKOUn4/edit#gid=0
Let me know if you have any questions or need anything clarified.
