Explanation

In the context of Cisco UCM SSO and IWA configuration, the two supported authentication protocols are Kerberos (D) and Digest Authentication (B). Kerberos is the preferred and primary protocol - it uses tickets issued by Active Directory's Key Distribution Center (KDC) to authenticate users transparently without transmitting passwords. Digest Authentication provides a fallback challenge-response mechanism using hashed credentials when Kerberos is unavailable. NTLM (A) is a Windows challenge-response protocol not used in this Cisco IWA context. SAML (C) is a separate SSO federation standard, and Smart Card (E) is a hardware-based authentication method, neither of which is part of IWA's core protocol set here.
