To install an OES server in a tree, you must have rights to extend the schema, meaning that you need Supervisor rights to the root of the tree.
You can extend the schema by using the Novell Schema Tool in YaST or by having a user with Supervisor rights to the root of the eDirectory tree install the first OES server and the first instance of each OES service that will be used into the tree. For more information, see Section 2.5.4, Extending the Schema.
If you are installing the server into a new tree, the Admin user that is created during the OES installation has full rights to the root of the tree. Using the account for user Admin allows the installer to extend the eDirectory schema for OES as necessary. To install the first OES server in an eDirectory tree, you must have the Supervisor right at the root of the eDirectory tree.
By default, the first three servers installed in an eDirectory partition automatically receive a replica of that partition. To install a server into a partition that does not already contain three replica servers, the user must have either the Supervisor right at the root of the tree or the Supervisor right to the container in which the server holding the partition resides.
