# FreeIPA requires over 2Gb+ in /usr - Change to root, Check DNS
|
|
# REPLICA - Server A can be installed with a CA and DNS services, while Replica A can be based on Server A's configuration but not host either DNS or CA services. Replica B can be added to the domain, also without CA or DNS services. At any time in the future, a CA or DNS service can be created and configured on Replica A or Replica B.

User2 rob0: I *think* freeipa has a named DLZ module that pulls records straight from LDAP
|
|
User2 not 100% sure (I know Samba does exactly that for AD-hosted zones, however)
|
|
User3 Does it work with IXFR queries, do you know? And I suppose UPDATE queries make the change in the LDAP backend?
|
|
User2 never tried IXFR, but yeah, Windows AD hosts heavily use UPDATE queries for self-registration
|
|
User2 usually with GSS-TSIG
