Shared pipeline gate for STUN/TURN methods that require credentials.
What problem this solves
TURN must verify that the client holds valid credentials before creating or using an allocation. This action checks nonce freshness, username/password (or access token), password algorithms, and MESSAGE-INTEGRITY on each protected request.
Runs before Allocate, Refresh, ChannelBind, CreatePerm, Connect, and ConnectionBind in their respective pipeline chains.
Internal
Pipeline action only; not part of the public application API.
