You must create a service principal for Oracle Database before the server can validate the identity of clients that authenticate themselves using Kerberos. Step 2: Configure a Service Principal for an Oracle Database Server.Oracle provides guidance for common Kerberos configuration problems. Troubleshooting the Oracle Kerberos Authentication Configuration.You can configure fallback behavior (password-based authentication) in case the Kerberos authentication fails. Configuring Kerberos Authentication Fallback Behavior.You can configure Oracle Database to interoperate with a Microsoft Windows 2008 domain controller key distribution center (KDC). Configuring Interoperability with a Windows 2008 Domain Controller KDC.Connecting to an Oracle Database Server Authenticated by KerberosĪfter Kerberos is configured, you can connect to an Oracle database server without using a user name or password.The Oracle Kerberos authentication adapter utilities are designed for an Oracle client with Oracle Kerberos authentication support installed. Utilities for the Kerberos Authentication Adapter.This section explains how to configure Active Directory, Identity Server, and Access Gateway for Kerberos authentication to a protected web server.To enable Kerberos authentication for Oracle Database, you must first install it, and then follow a set of configuration steps. This enables seamless authentication (single sign-on) to Identity Server from enterprise-wide Microsoft Windows Domain Logon. The Kerberos module for Access Manager is implemented to securely negotiate and authenticate HTTP requests for protected resources. SPNEGO's most visible use is in Microsoft's HTTP Negotiate authentication mechanism. It enables peers determine which GSSAPI mechanisms are shared and enables them select one and establish a security context with it. SPNEGO (RFC 2478 - Simple and Protected GSSAPI Negotiation implementation in Microsoft Windows 2000/XP/2k3/2k8) is a GSSAPI mechanism for extending a Kerberos single-sign-on environment to web transactions and services. Kerberos authentication is achieved using SPNEGO with GSS-API (JGSS). This provides single sign-on for the user between Active Directory and Identity Server. You can configure Identity Server to use this token as a contract. This authentication method provides a token. Kerberos is an authentication method that allows users to log in to an Active Directory domain.
