Example of Process Authentication
The following simple example of communication between an RPC client
and an RPC server illustrates the OVO procedure for process
authentication:
1. Reads Password
The message agent (RPC client) reads its password from the key file.
2. Logs In
The message agent uses the password to log in to the security server,
procure a login context, and obtain a server ticket.
3. Sends Request
The message agent sends an RPC request to the message receiver
(RPC server).
4. Verifies Request
The message receiver compares the ticket with the password
contained in the key file.
5. Approves Request
If the password matches, the message receiver tells the message
agent to proceed with its RPC request.
In this example, the RPC client is the message agent on the managed
node, and the RPC server is the message receiver on the management
server
About Process Authentication Requirements
In OVO, the management server and the managed nodes run RPC
clients and servers at the same time. By running PRC clients and servers
simultaneously, OVO is able to limit the requirements of each process for
configuration information prior to an RPC call.
Each OVO process requires the following configuration information:
❏ Name and password
❏ Security level
This configuration information must be present on both the management
server and the managed node.
