Real‑World Scenarios & Fixes

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

|---|---|---|

| 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| NAS crashes | Outdated firmware | Update firmware; reset connector; retry login |
