Decoupling Authentication, Coarse-grained and Fine-
grained Authorisation Realms
The following diagram shows how the consistent use of a User UUID makes
it easy to manage the Authentication and Authorisation requirements of
different (even overlapping) groups of users with absolute flexibility in the
choice of products at each level. (Of course, if an associated system cannot
hold a UUID reference, then the IAM database must hold the mapping.)
