Maybe I didn't really get the concept but basicly if you say you're compatible with SCIM then there must be certain expectations of properties that belong to identities am I right?
For an example if you take a look at the example createUser request from
https://developers.onelogin.com/scim/implement-scim-api
you will see a variety of different properties like displayName, nickName etc..
My use case however requires only one name, the userName.
My question is, are any of these even required to say that you are SCIM compliant?
