I’m having a perplexing problem: even after attaching an AWS-managed policy (such AmazonS3FullAccess) to an IAM user, the user continues to receive AccessDenied when attempting to use the CLI or terminal.
I looked for explicit denials, session policies, permission restrictions, and SCPs, but nothing caught my attention.
Has anyone ever encountered a scenario where access is denied by AWS even if permissions appear to be correct?
What more should I look for?
