I note that LDAP is still basically X.500, and this informal definition is invalid in pure X.500 terms. You should dispense with the notion of prefix and just make this a regular DN, with a constraint that the DN will be subordinate to the containerInfo entry.

The point of XDR blobs is that a file server doesn't need to un-marshall then re-marshall the pathname data when it generates a referral. Replacement suggestions welcome.

Also your definition provides absolutely zero information of how the LDAP server should be contacted (e.g. using ldaps or StartTLS) which both can be encoded in an LDAP URL. It also precludes the use of ldapi:// which might be preferred for an inward-facing/local agent.

This draft has been in last call for months, I'm surprised there are so many issues. I think there is still an opportunity for discussion on the working group mailing list. We welcome your comments on firstname.lastname@example.org.
