We have one provider and one consumer running syncrepl. All of our important clients are using sssd, configured to cache everything, with the consumer set as secondary ldap server. I have verified that everything works properly in sssd if the provider goes offline. Can I flip the provider to hdb, or mdb, and keep consumer as bdb, with syncrepl still running, then later change the consumer?
Yes. LDAP is a protocol. It doesn't care what the underlying storage DB is. So you could have a back-hdb master and a back-mdb consumer, etc.
