vPro AMT can leverage Kerberos authentication to allow management from your management console to the AMT firmware. Depending on the management console of choice (e.g. SCCM, Altiris, SMS) you may be using Kerberos or digest authentication.

In AMT (version 2.x, 3.x, 4.x, and 5.x) there is a Kerberos ticket size limit that varies among versions of AMT (see graph 1 below on specifics for each firmware version). With respect to Kerberos authentication, AMT has different limits for HTTP connection and Serial-Over-LAN (SoL).
