We support the Krb5PrincipalName OtherName SAN already, even in the
default profile**.  It must be included in the PKCS #10 CSR (per
instructions at MIT page above) and values are validated by FreeIPA
before passing to Dogtag.

** Key Usage / Extended Key Usage would probably not be appropriate
   for user certs, though.

There's a ticket for "CSR templates"[1] to make doing this sort of
thing easier.  Eventually I would like to have profiles that don't
need any special info in the CSR but just read data from the
directory.
