About Application Protocols, Authenticated Connections, and Domain Controllers
SteelHead accelerates several application-specific protocols. Acceleration of secure traffic may require communication between the server-side SteelHead and domain controllers. We recommend using WinSec Controller, which is purpose-built for secure environments and complies with Microsoft’s tiered security model, to facilitate that communication. Otherwise, you’ll need to join the server-side SteelHead as a trusted entity on the relevant domains for New Technology LAN Manager (NTLM) or configure replication users for Kerberos.
Enabling acceleration, or changing any of the protocol settings, generally requires a service restart.
Acceleration for some protocols on some models may require a separate license. For appliances with feature-tier licensing, generally you can configure and enable acceleration even if the feature is not licensed; however, the feature needs to be both enabled and licensed to work.
