IMO it is not important for FreeIPA 4.4.  It is nice to have but I
doubt it will make it.


Honza suggested it should be the other way around, i.e. CA specifies
default profile rather than profile specifies default CA.

The fact (also raised by Christian) is that multiple profiles may be
used with a single CA, and vice-versa.  CA ACLs will govern what
combinations are acceptable.

Thinking from user perspective, there are a couple of things to

- Currently, to request a particular kind of cert, user must specify
  a profile ID.

- It is more natural to ask for a particular profile and have the
  request dispatched to a profile-specified default CA, than to ask
  for a cert issued by a particular CA, and a CA-specified default
  profile will be used.

Given these points, I am strongly in favour of having the profile
indicate the default CA - not the other way around.

My worry is how will this work when external CA support comes into the picture (I outlined a possible solution at [1]).

Right now there is only Dogtag, so all profiles work for all CAs, but once there are different types of CAs, this will no longer be true, because profiles are inherently CA implementation-specific.

I'm not against profiles having a default CA per-se, I would just like the design to take the possibility of external CAs into account, so that it does not create issues for us in the future.
