Re: DN->DNS mapping in draft-ietf-ldapext-locate-05.txt

[jkk@coreon.net]

I've run across the need to do exactly what is mentioned below (although the
acutal implementation is slightly different)...the ability to use
dc=customer,dc=com,o=customers,dc=mycompany,dc=com becomes very powerful when
managing/maintaining lots of customer DNS RRs.

That being said though, as an SP we are not managing DNS RRs that way but
instead doing something like fqdnATTR=customer.com,o=customers,
dc=mycompany,dc=com.  Although this probably isn't quite as scalable as 
grouping domains based on their gTLD, it became a tossup between scalability 
and buisiness requirements/ease of use.

I would like to see a common DN structure defined which would allow easier
interoperability with other DITs...however I can also see where this 
could potentially limit companies with different business models from being
able to use this structure (and therefore lose the ease of integration).
I therefore think it should be kept as loose as possible even though the
integration point could be lost.

Just my $0.02.
