Ok, thanks @pepov -- that clears up the intention of these changes to me.
For naming of variables/properties I'm good with either _identity_ or
_name_, as you suggest - both are clear to me and distinct from _identifier_. I
was more concerned with the usage of the method
`UserGroupProvider.getGroup(String groupIdentifier)`, which will will have to
change if the value is not actually an identifier.
For accessing users, the
[UserGroupProvider](https://github.com/apache/nifi/blob/master/nifi-framework-api/src/main/java/org/apache/nifi/authorization/UserGroupProvider.java)
interface provides both `getUser(String identifier)` and
`getUserByIdentity(String identity)` methods. I don't see an equivalent method
for groups that is a lookup by name/identity, so you'll have to work around
that.
