The Entra SCIM tutorial told readers to leave `emails[type eq "work"].value` at its default Direct mapping from `mail`. Microsoft documents that `mail` "is only populated if the user has a Microsoft Exchange Mailbox," and that Entra skips null attributes rather than sending them, so users without a mailbox sync into Smallstep with no email address at all. SSO login matches users by email, so those users appear correctly provisioned in the directory but cannot sign in — they get "You are not authorized to access this account," which also wrongly suggests email/password as a fallback that directory users do not have. Map the attribute through `Coalesce([mail],[userPrincipalName])` instead — Microsoft's own documented example for exactly this case — and link the reference docs. Also note that mapping changes require Restart provisioning to reach already-synced users, and add a troubleshooting entry for the sign-in failure. The screenshot in graphics/entra-id-mappings.png still shows the `mail` mapping; the text now calls that out until it can be retaken.
