X-MS-CLIENT-PRINCIPAL-NAME has disappeared in the header

Voronin Sergey FR 0

Hello,

I manage an Azure App Service that handles requests from authenticated users within our subscription. Until recently, everything was functioning seamlessly. However, I’ve encountered an issue where the emails that typically appear in the X-MS-CLIENT-PRINCIPAL-NAME header have suddenly disappeared.

import panel as pn

pn.state.headers.get("X-Ms-Client-Principal-Name")

Could you please share any potential workarounds?

Thank you,

Sergey

Hi @Voronin Sergey FR were there recent changes made to your subscription?

If you're using the built-in Easy Auth feature of Azure App Service, the X-MS-CLIENT-PRINCIPAL-NAME header should be populated automatically. However, if you're using custom authentication logic, you may need to set the header manually in your code.

It also happened to me.
Try to STOP and then START the service. RESTART did not help.
Now the tag is visible again.
