As a result of the email discussion about LDAP, it was suggested by Tim Howes that a separate document be envisaged: Guidelines for X.500 "clients" implementation. This proposal was done within the LDAP context, with 2 goals in mind: - how to make efficient use of the LDAP set of available operations - avoid implementation dependencies. This issue was discussed during the WG-NAP meeting in Trondheim, and I suggested that the goal should have to be larger. I am really convinced that this guidelines document has to be prepared for X.500 "clients" in general and not limited to LDAP, because our experience with several different implementations has shown that many existing X.500 clients are still designed without a clear view on the impact of the algorithm used on - specific impementations - specific structuring and distribution of the DIT over different DSAs Of course a specific section will have to be devoted to LDAP and its set of operation, but this will only have to cover what is specific to LDAP (not too much in my mind). The last message from Steve Kille, when talking about 1rst and 2nd generation DUA, highlights the evolution (gained from experience) of X.500 clients algorithms (BTW this TERM seems to me more appropriate than DUA for this purpose). It is really time to share and write down our experiences in that area, because it does not only have a great impact on "clients" design, but also -- and probably even more important- a very high impact on the design of the servers (DSA) themselves. As our goal is "success" and "deployement" of X.500, it is of the highest importance that, as soon as possible, our community is provided with an efficient X.500 infrastructure (ie. clients + servers). To reach this goal it is mandatory that the - Client designers/implementors are well aware of the servers behaviour - Server designers/implementors are well aware of the clients behaviour and requirements. I don't know how this concretely could be handled, but given the importance and consequences I suggest this activity be started as soon as possible and associates all "players" ie. at least osi-ds, wg-nap, and paradise interworking group. Steve, any suggestion? BTW: Tim Howes will give a lecture here and participate to a working meeting (May 27th and 28th) and we have planned to start discussion about this. Thus some contribution might be expected as an early outcome. Steve, would it be possible to have this item be part of the OSI-DS agenda in Amsterdam? best regards, -- PAP ~h
