How do you test SSO role mapping before a wider rollout?

emorris

A SaaS workspace is moving to single sign-on, and the identity provider sends group information used to assign application roles. The mapping looks straightforward, but missing attributes or overlapping groups could produce surprising access.

What test cases would you run before inviting the broader team? I am especially interested in new users, role changes, removed group membership, and users who belong to multiple groups. How would you verify the final permissions rather than checking only that sign-in succeeded?

Create a small test matrix with expected permissions for each group combination, including no matching group. Test role changes and removal as well as first sign-in, and check the resulting permissions inside the application. Also test the documented recovery path for administrators. A successful authentication should not be the only rollout criterion.
