Real‑World Scenarios & Fixes

“App launch failed – correlation ID”

Cause: Partial consent or Conditional Access block.

Fix: Re‑grant full consent, verify all permissions, review CA policy exclusions.

“Consent granted but NAS cannot list files”

Cause: Assignment required = Yes without user assignment.

Fix: Disable assignment requirement or assign the service account explicitly.

“Popup closes instantly”

Cause: OAuth redirect/cached session conflict.

Fix: Use direct admin‑consent URL, clear Microsoft cookies, update NAS firmware.

Troubleshooting Matrix

Symptom Likely Cause Solution
Consent loop Missing/partial scopes Grant admin consent; confirm Files.ReadWrite.All, Sites.ReadWrite.All
Access denied Assignment required Disable assignment or add service account
Blocked sign‑in Conditional Access Meet MFA/device requirement or add exclusion
NAS crashes Outdated firmware Update firmware; reset connector; retry login

FAQ

Is admin consent identical globally?

Yes, Entra ID model is global; compliance policies differ by country.

Can I pre‑approve apps for subsidiaries?

Yes, approve at tenant root, set Assignment = No, or assign groups as needed.

How to avoid downtime?

Schedule changes in maintenance windows; test with pilot groups first.

What hardens backup security?

Dedicated accounts, MFA, IP/geo restrictions, token refresh reviews, up‑to‑date firmware.
