The Administrator user that you specify as the Proxy User during OES Cluster Services install process is automatically configured as the administrator for the cluster with the following setup:
The user is a trustee and has the Supervisor right to the Server object of each server node in the cluster.
The user is enabled for Linux with Linux User Management. This gives the user a Linux UID in addition to the users eDirectory GUID.
The user is a member of a LUM-enabled administrator group associated with the servers in the cluster.
IMPORTANT:To allow other administrators (such as the tree administrator) to manage the cluster, the users’ user names must be similarly configured.
You can modify the default administrator user name or password after the install by following the procedure in Section 8.13.1, Changing the Administrator Credentials or LDAP Server IP Addresses for a Cluster.
