Subject: [PATCH] Prohibit deletion of included profiles

Deletion of included profiles, including the default profile, should
not be allowed.  Detect this case and raise an error.

Also update the included profiles collection to use namedtuple,
making it easier to access the various components.

I think you also want to protect the included profiles from renaming.

This is already the case.
I'm also wondering about certprofile-mod changing the profile content
and changing profileID there to point to existing profile. Would this
affect CA operation?

Renaming profile / changing profile-id / pointing it to a different
profile is not possible.

Changing profile content *is* currently possible.  Given that we
have custom profiles now, there is an argument to be made that we
should prevent profile-mod for updating the Dogtag configuration of
predefined profiles.

If we did that, we would probably also want to allow admins to
change which is the default profile, i.e. changing the default to
some custom profile they added.

And if we did that, then perhaps we should let them specify a
different default profile for users vs hosts/services!

How deep does this rabbit hole go? :)
All the above makes sense and should be done in terms of proper
hardening and usability fixes. I don't think it is a bottomless hole,
though, just a normal work we have to do to make certificate profiles
nice and usable :)

Right; I'll file tickets for these explored regions of the hole, and
leave the unexplored depths for another day.
