Hi Rob,

I was considering installing replicas using puppet.  Having pre-prepared 
replica files available would be easier than having to run an 
ipa-replica-prepare and scp copy.

I had guessed the ldap/kerberos replication would handle the user/password/DNS 
updates, and that changing CA certificates would be the most likely cause of 
gpg file invalidation.   

Again, thank you for speedy response and clarification!

Cheers, Dave
