C Integrating Enterprise User Security with Microsoft Active Directory

Enterprise users make use of Oracle Internet Directory, which is a part of the Oracle Identity Management infrastructure. If your organization uses a third party directory like Active Directory to store and manage user entries, then you can integrate it with Oracle Internet Directory to manage Enterprise User Security.

Kerberos authentication for enterprise users can make use of tickets issued by a kerberos Key Distribution Center (KDC) running on a Microsoft Windows domain controller.

This appendix lists the steps involved in integrating Enterprise User Security with Microsoft Active Directory using kerberos for authentication. It includes the following sections:

C.1 Set Up Synchronization Between Active Directory and Oracle Internet Directory

Oracle components make use of Oracle Internet Directory for centralized security administration. Your organization might have a Microsoft Windows domain that uses Active Directory for centralized administration. You should set up synchronization between Oracle Internet Directory and Active Directory before you configure Enterprise User Security to work with Active Directory.

Synchronization profiles are used to synchronize the two directories. The profile contains configuration information required to synchronize the two directories. This includes direction of synchronization, mapping rules and formats, connection details of Microsoft Windows domain and the like. Mapping rules contain domain rules and attribute rules to map a domain and attributes in one directory to the other directory, optionally formatting the attributes.

C.2 Set Up a Windows 2000 Domain Controller to Interoperate with Oracle Client

The following tasks must be performed on the Windows 2000 domain controller:

  1. Create the Oracle Database Principal in Microsoft Active Directory

    This creates a new user for the database in Microsoft Active Directory.

  2. Use the ktpass command-line utility to create a kerberos keytab file

    The ktpass utility is a part of the Windows 2000 Support Tools. The keytab file is required to use a Windows 2000 domain controller as a KDC.

  3. Copy the keytab file created in the previous step to the computer on which the database server is installed

C.3 Set Up Oracle Database to Interoperate with a Windows 2000 Domain Controller

The following task must be performed on the host computer where Oracle Database is installed:

C.4 Set Up Oracle Database Client to Interoperate with a Windows 2000 KDC

The following steps must be performed on the Oracle kerberos client:

  1. Create client kerberos configuration files

    The client kerberos configuration files refer to the Windows 2000 domain controller as the kerberos KDC.

  2. Specify kerberos parameters in the client sqlnet.ora file

    You can either manually update the file or use Oracle Net Manager utility.

C.5 Obtain an Initial Ticket for the Client

Before a client can connect to the database, the client must request for an initial ticket. The initial ticket identifies the client as having the rights to ask for additional service tickets. An initial ticket is requested using the okinit command.

Oracle Database Advanced Security Administrator's Guide for more details on requesting an initial ticket with okinit.

C.6 Configure Enterprise User Security for Kerberos Authentication

To configure Enterprise User Security for Kerberos Authentication, use the following steps:

  1. Register the database in Oracle Internet Directory

    You can use Database Configuration Assistant for registering the database.

  2. Configure Enterprise User Security Objects in the database and Oracle Internet Directory

    Create global schemas and global roles in the database. Also create enterprise roles in the enterprise domain. Configure user schema mappings for the enterprise domain, add global database roles to enterprise roles and grant enterprise roles to enterprise users for database access.

  3. Configure the enterprise domain to accept kerberos authentication

    Use the Enterprise Security Manager to enable kerberos authentication for your enterprise domain.

  4. Connect as kerberos authenticated enterprise user.

    Launch SQL*Plus and use the command, connect /@net_service_name to connect as a kerberos authenticated enterprise user.
