Schema installer
Bundled with the schema installer are one or more .xml files. These files contain the schema that will be
added to the directory. Typically, one of these files will contain core schema that is common to all the
supported directory services. Additional files contain only product-specific schemas. The schema installer
requires the use of the .NET framework.
The installer includes three important screens:
• Schema Preview
• Setup
• Results
Schema Preview
The Schema Preview screen enables the user to view the proposed extensions to the schema. This screen
reads the selected schema files, parses the XML, and displays it as a tree view. It lists all of the details of
the attributes and classes that will be installed.
Setup
The Setup screen is used to enter the appropriate information before extending the schema.
The Directory Server section of the Setup screen enables you to select whether you will be using Active
Directory or eDirectory, and to set the computer name and the port to be used for LDAP communications.
IMPORTANT: Extending the schema on Active Directory requires that the user be an authenticated Schema
Administrator, that the schema is not write protected, and the directory is the FSMO role owner in the tree.
The installer will attempt to make the target directory server the FSMO Schema Master of the forest.
To get write access to the schema on Windows® 2000 requires a change to the registry safety interlock. If the
user selects the Active Directory option, the schema extender will attempt to make the registry change. It
