Patch descriptions .. in reverse order.
Note that the CA setup for authz is further documented at

section on 'CA Configuration".

    Add realm to requests coming in from CA
    
    Requests to the KRA through the CA-KRA connector use the Enrollment
    Service.  This has been modified to read and store any realm passed in.
    The realm can be added to the request by havibg the admin add
    a AuthzRealmDefault and AuthzRealmConstraint in a profile.
    
    At this point, all the constraint does is verify that the realm is
    one of a specified list of realms.  More verification will be added
    in a subsequent patch.
    
    No attempt is made yet to allow users to specify the realm.  This
    would need to be added as a ProfileInput.
