No, we do not have any shadow map in ipa, enforcement of password and
account expiration is done by the server, not deferred to the clients.

What are you looking for in the shadow map ?

This was true for ipa v1 only where we used a selfsigned CA available
only in the first master, since v2 you are supposed to use the dogtag
PKI, so if you clone the PKI as well (you need to explicitly set it up,
by default replicas do not replicate the CA) you have full redundancy
with regard to network facing data.

If you are using the dogtag CA it wouldn't as it uses a DS instance as
well. If you are using the selfsigned CA well, I guess you have no other
option.

Simo.
