Shib with Multiple AWS Accounts

[Jim Fox]

We do this as well.  We use groups named (grouper syntax) 
"u:weblogin:aws:<account-number>:<role-name>" 
Then we send all the accounts and roles where a user is a member of the corresponding group.

If the user is in multiple accounts and/or roles, AWS lets them choose upon login. I can't see a reason to have separate login links.

I suppose you could bake in something proprietary into the system to signal this but that's heavy work that would have involve webflow customization if not even deeper manipulation of the system.
