Scope and fit
Single sign-on simplifies user lifecycle management but can become a service dependency. Recovery should be designed and tested without leaving permanent shared administrator credentials.
Document federation trust
Record issuer, audience, signing keys or certificates, claim mappings, group rules, and contact ownership. Review changes to identity-provider metadata and application callback settings.
Test failure and renewal scenarios
Exercise expired signing material, changed claims, provider outage, and staff lockout in a controlled environment. Confirm how users are notified and how access returns to normal.
Control local and emergency accounts
Disable unnecessary local authentication or restrict it to a reviewed emergency process. Monitor use, store credentials securely, and rotate them after recovery; do not bypass the identity provider indefinitely.

Implementation questions
What should the team decide about document federation trust?
Record issuer, audience, signing keys or certificates, claim mappings, group rules, and contact ownership. Review changes to identity-provider metadata and application callback settings. Use a named owner and a written acceptance check so this decision can be reviewed after deployment.
What should the team decide about test failure and renewal scenarios?
Exercise expired signing material, changed claims, provider outage, and staff lockout in a controlled environment. Confirm how users are notified and how access returns to normal. Use a named owner and a written acceptance check so this decision can be reviewed after deployment.
What should the team decide about control local and emergency accounts?
Disable unnecessary local authentication or restrict it to a reviewed emergency process. Monitor use, store credentials securely, and rotate them after recovery; do not bypass the identity provider indefinitely. Use a named owner and a written acceptance check so this decision can be reviewed after deployment.
Plan, build, verify, operate
Document federation trust: Record issuer, audience, signing keys or certificates, claim mappings, group rules, and contact ownership. Review changes to identity-provider metadata and application callback settings. Record the result and the next owner before changing the next boundary.
Test failure and renewal scenarios: Exercise expired signing material, changed claims, provider outage, and staff lockout in a controlled environment. Confirm how users are notified and how access returns to normal. Record the result and the next owner before changing the next boundary.
Control local and emergency accounts: Disable unnecessary local authentication or restrict it to a reviewed emergency process. Monitor use, store credentials securely, and rotate them after recovery; do not bypass the identity provider indefinitely. Record the result and the next owner before changing the next boundary.
Deployment checks
Turn the page into a reviewable handover by assigning each check to a person and retaining its result.
Plan for SSO Federation Failure Without Creating a Backdoor: decision 1
Write down the boundary, owner, dependency, and proof required for plan for sso federation failure without creating a backdoor before implementation begins.
Plan for SSO Federation Failure Without Creating a Backdoor: decision 2
Write down the boundary, owner, dependency, and proof required for plan for sso federation failure without creating a backdoor before implementation begins.
Plan for SSO Federation Failure Without Creating a Backdoor: decision 3
Write down the boundary, owner, dependency, and proof required for plan for sso federation failure without creating a backdoor before implementation begins.
Handover and ownership
Before handover, name the system owner, support path, access boundary, backup or recovery responsibility, and the condition that pauses a change.
Keep a short record of what was tested, what remains outside scope, and when the review should happen again.
