Note the following limitations: * Oracle provides support for Microsoft Active Directory only on Windows operating systems. Therefore, client computers and the database server must also run on Windows operating systems to access or create entries in Microsoft Active Directory. * The following features are not supported by Microsoft Active Directory: * Multiple Oracle Contexts Microsoft Active Directory can support only one Oracle Context. * Net service aliases You cannot create net service aliases in Microsoft Active Directory. However, you can create net service names. * Automatic client discovery of directory servers for clients You must statically configure directory server usage on the clients. The Oracle Internet Directory Configuration will not provide directory server usage for Microsoft Active Directory. You must use Oracle Net Configuration Assistant <http://download-west.oracle.com/docs/cd/B19306_01/network.102/b14212/gl ossary.htm#i1000122> . ________________________________ From: Allen, Brandon Sent: Tuesday, February 27, 2007 10:59 AM To: 'niall.litchfield@xxxxxxxxx'; goran00@xxxxxxxxx; mgogala@xxxxxxxxxxx; oracle-l Subject: RE: Tnanames.ora http://download-west.oracle.com/docs/cd/B19306_01/win.102/b14304/active_ dir.htm#CDECHCBC Directory Naming Software Requirements For client computers from which you want to manage Oracle Database enterprise users, roles and domains, you must have Oracle8i Client release 8.1.6 or later and one of the following Microsoft products: * Windows XP * Windows 2000 * Windows Server 2003 For the database, you must have Oracle8i Database release 8.1.6 or later.
