Introduction to Authentication Mechanisms

This chapter describes the following features:
  • Internal authentication mechanisms unify the SAS realm and provide a degree of independence from your general computing environment. The internal mechanisms are SAS internal authentication and SAS token authentication.
  • External authentication mechanisms integrate SAS into your computing environment. External mechanisms include direct LDAP authentication, host authentication (credential-based), Integrated Windows authentication, and Web authentication.
  • Credential management provides single sign-on through reuse of cached credentials or retrieval of stored passwords.
  • Pluggable authentication modules (PAM) extend UNIX host authentication.
  • Trust relationships facilitate communication to the metadata server by permitting one privileged account to connect on behalf of other users (trusted user) or by accepting requests that use a proprietary protocol (trusted peer).
