How would one enroll with multiple IPA servers? For instance, a standard
configuration for a Rocks HPC cluster is to have at least two and usually three
networks active, with different DNS zones for each. The "public" network is
"company.example.com", "private" is typically an isolated GbE network named
"local", and there's usually a fast network for real work (Infiniband or
10GbE); let's name it "ipoib" for IP over Infiniband. There may also be a slow
100bT network for management.
A few machines have access to all three networks (headnode.company.example.com,
headnode.local, and headnode.ipoib). Compute nodes have access to two
Is it possible to make a single IPA instance manage the two isolated networks
(local and ipoib)? Would multiple IPA servers and multiple enrollments be
required? Once an IPA solution is defined, how does one configure
openssh/sssd/krb5 on the compute nodes such that Kerberos SSO (and NFS server
access) works regardless of which isolated network is used for communication?
Would the compute nodes' two-network configuration be extensible to the
headnode's three-network configuration?
