Product bug (s) ID, or bug(s) link: (e.g. Windows SE:123456)
Symptoms
The Kerberos client requests a ticket to a resource that has an associated authentication policy, which will only allow access if the device is member of a specific group.
The request fails with a status of KDC_ERR_POLICY (0xc) and an extended status of STATUS_AUTHENTICATION_FIREWALL_FAILED (0xc0000413).
This only occurs when the client is using a renewed TGT for the TGS request.
Cause
This issue occurs when the TGT being used for the TGS request has been renewed.
When renewing the TGT the KDC does not set a flag in the ticket that allows it to be used for explicit armouring.
When the client uses the renewed TGT, it will not send explicit armouring that is required for the authentication policy to succeed.
