Section Number and Name:
2.1.4. Port Requirements
Describe the issue:
The Port Requirements section of the Linux Domain Identity, Authentication, and Policy Guide has the list of ports used, but it does not explicitly say the ports are for incoming connections to the IdM server.
This is vague "IdM uses a number of ports to communicate with its services. These ports must be open and available for IdM to work." It should state clearly where and in what direction the ports must be open.
Under "Opening the Required Ports" there are instructions on opening the ports in the host-based firewall. If the reader follows those then everything should work. However, it does not mention network-based firewalls. These must also be open and in that case its important to state if the traffic is bi-directional as not everyone is using stateful firewalls.
Suggestions for improvement:
Take a look at the Satellite Installation guide for some ideas on how to present port information and firewall commands.
