In ServiceNow, impersonation allows administrators to act as another user to troubleshoot, test permissions, or verify user experiences.
To log impersonation events in the System Log, the system property:
CopyEdit
glide.sys.log_impersonation
must be added and set to true (true).
Key Features of glide.sys.log_impersonation:
✅ Logs who impersonated whom in the System Log.
✅ Captures timestamp, user details, and session activity.
✅ Helps with auditing and security compliance.
How to Enable Impersonation Logging:
Navigate to System Definition > System Properties.
Search for glide.sys.log_impersonation.
If it doesn't exist, create it:
Name: glide.sys.log_impersonation
Type: True/False
Value: true
Save the property and test impersonation.
