Access and Synchronization of the Internet Directory BOF (ASID)
Reported by Tim Howes/University of Michigan
Background for this BOF
Tim presented a review of the Framework for a White Pages Service for
the Internet BOF (PAGES) held on Monday, along with the perceived need
for an ASID Working Group in the broader context of the WPS directory
service reorganization underway in the IETF. The PAGES BOF identified
the need for four groups:
o A short-lived requirements group (Tony Genovese)
o A policy/administration/legal issues group (IDS)
o An interoperability/indexing group (TBD)
o A protocol group (ASID)
ASID is the proposed protocol group, whose mission is to define and
evolve individual directory service protocols.
Review of Proposed Charter
There was some discussion about whether the synchronization part of ASID
was appropriate. Some people felt it was not a well-defined area and
that none of the group's milestones currently reflected a focus on this
topic. Others felt that synchronization was an important aspect of
Internet directory services which needed to be addressed by the IETF,
and that ASID was the place to do it. It was finally decided that ASID
would keep synchronization in its charter.
Tim took an action to make any minor charter changes required and send
it to the list.
Proposed Group Name
There were several suggestions for alternate names for the group:
PIDS Protocols for Internet Directory Service
CWPIDS (Unknown)
DASI Directory Access and Synchronization for the Internet
The final decision will be made on the mailing list.
Logistics - How Will this Group Work?
Given the broad set of protocols under the ASID umbrella, there was some
question as to how the group could best function in its ``coordinating
and reviewing'' capacity, while remaining focused enough on individual
protocols to get actual work done.
It was decided that individual protocols (e.g., WHOIS++, LDAP) should be
developed by smaller teams working on their own mailing lists (which in
many cases already exist). These groups would then bring their
documents to the ASID list for review.
SOLO Directory Service
Paul-Andre Pays gave a presentation on the SOLO directory service
(currently described in the Internet-Draft draft-huitema-solo-01.txt).
A lively discussion followed. Paul-Andre stated that a future version
of the document would flesh out various issues such as schema, query
syntax, etc.
LDAP
Simon Spero presented some comments on the LDAP Proposed Standard. The
comments were editorial things he had encountered in doing a second
independent implementation of LDAP. Tim will make the suggested changes
and resubmit the draft.
LDAP has been at Proposed Standard since July of 1993. Since there are
now two independent interoperable implementations, the feeling of the
group was that it was time to move LDAP to Draft Standard. Erik Huizer
was tasked with pursuing this.
CLDAP
The Connectionless LDAP draft by Alan Young seems to have taken on a
life of its own, generating much discussion on the OSIDS list and in the
meeting. There was a generally identified need for a connectionless
version of LDAP, but among the issues still needing to be resolved were:
o How do we fit multiple results in a single packet
o How do we fit multiple requests in a single packet
o Should we leave out modifies
o How small does it need to be (e.g., to fit certificates)
The group felt modifies were not needed. People can use LDAP if they
want to do modifies/creates/deletes.
The last question about size of the packets produced much discussion and
lots of space-saving ideas, including using ``packed encoding rules,''
replacing attribute names by well-known numbers, and using some form of
compression.
It was finally decided that we did not have a good handle on the
requirements for such a protocol in terms of size. Simon was
volunteered to write up his views on size requirements and send them to
the list.
Date of Next Meeting
The next meeting of ASID (its first as a real working group) will be at
the July IETF in Toronto, Canada.
