Will AWS SSO conflict with IAM ID provider?

Hi Al,

If you start using SSO your existing integrations with IAM will not be impacted.

When you use SSO a new IdP(Identity provider) with the name format: "AWSSSO_e1234a56b0b90f8b_DO_NOT_DELETE" is created.

After this when you create permission sets and assign them to user, the roles corresponding to these permission sets are then created in IAM with the following name format:-
This role was created for the permission set name: AdministratorAccess= "AWSReservedSSO_AdministratorAccess_e12a34c56dfb478a"

These roles then have a trust relationship policy which trust the Identity provider created by SSO.

I hope this answers your query.
