Issue Description
The issue was reported after the system had been working normally earlier in the day, indicating a sudden login failure affecting multiple users.
Impact
- Users could not sign in to the system
- Affected multiple users at the same time
- The system appeared functional earlier before the issue occurred
Root Cause
Observed some exception errors in the logs and reviewed them with the operations team, and found out that the issue occurred because system user accounts were disabled.
These accounts are essential for system authentication and core functionality. When they were disabled, the system was unable to process user login requests, resulting in login failures.
Resolution Steps
- Identified that system user accounts were disabled
- Re-enabled the required system user accounts
- Verified system authentication service was working
- Confirmed users were able to log in successfully after the fix
Prevention Steps
- System user accounts should not be disabled, as they are critical for authentication and essential system operations.
