From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i686) When installing 7.1 with medium or higher firewall configured AND configuring to use NIS to authenticate users, ypbind fails to bind to the NIS server causing login to the system to fail for NIS based accounts. Reproducible: Always Steps to Reproduce: 1. Install RH 7.1 2. Select medium or higher firewall level 3. Select NIS for authentication and enter the IP address of the NIS server. Actual Results: ypbind fails to bind to the NIS server. Any users attempting to login to the system where their account resides only in NIS will fail. Expected Results: The firewall rules should be setup such that if the user selects authentication to be performed via NIS, the rules should be modified to allow ypbind to bind to the NIS server.
The firewall screen is designed to allow you to set a security level...nothing more. We had rather err on the side of caution and security than the other way around.
