Authentication Mechanisms

Introduction to Authentication Mechanisms

This chapter describes the following technologies, features, and trust relationships:

Internal 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 mechanisms integrate SAS into your computing environment. External mechanisms include direct LDAP authentication, host authentication (credential-based), Integrated Windows authentication, and Web authentication.
Supporting features for credential-based authentication include the following:
- 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).
