Adaptive Server uses the Server User Identity (SUID) to uniquely identify a user with a login account name. This identity is linked to a particular User Identity (UID) in each database. Access controls use the identity when determining whether to allow access for the user with this SUID to an object. Authentication verifies that a user is actually the person they claim to be. Adaptive Server allows both internal and external mechanisms for authentication.
Identification and authentication controls are discussed in Chapter 14, “Managing Adaptive Server Logins, Database Users, and Client Connections.” In addition, see “Using proxy authorization” and Chapter 15, “Managing Remote Servers.”
