Subject: scenarios for Directory Synchronization
Hi, I have beed reading the discussion on Directory Synchronisation with lot of interest. Here, I would like to share some of my views. I feel that we have been mixing up two scenarios (as defined below). We need to first understand the scenario which we are talking about???? ++++++++++++++++++++++++++++++++++++++++++++++++++++++ SCENARIO-1 : Use of a corporate Directory service ---------- Here, X.500 directory service is used as part of Global and corporate directory service. Corporate Directory Service is used for lot of corporate requirements, such as: * Personnel profiling of an employee * For lookup of Telephone number, Fax Number, E-mail address, common name, description etc. etc. * For storing sensitive "secure" information such as private and public encryption keys etc. * To offer white page and yellow page service for employees and corporate network * to provide Whois services etc. In fact, in this case, Directory is a very important corporate resource and one needs to build process and procedures to maintain it very carefully. In this case, DNs are to be defined at the time of person joining the organisation. DNs have to be a kind of an identity (like employee number) of the person. Several mechanism, including directory synchronisation, are required to be developed to maintain "Corporate directory". Clearly, this will require a very strong commitment and awareness at the organisational level. Also, a very simple and easy-to-use browsing mechanisms will be required to support such a directory. SCENARIO-2 : Using X.500 for e-mail address resolution in Global and ---------- distributed manner This scenario is, clearly, a subset of "scenario-1". However, this requires low commitment at organisational and corporate level. Here, X.500 directory DNs CAN BE generated as a "rule based approach" from LAN / legacy Email accounts. This can become part of Directory synchronisation mechanism. In this case, X.500 directory is used by Email Gateways to resolve LAN / Legacy e-mail addresses to X.400 or-address OR DN and vice versa. Also, X.500 directory will be used by X.400 (1988) MTA and (optionally) by UA for Mail routing etc. In this case, X.500 directory is can only be used as white page or yellow page service for the end-user Email accounts. However, it will not be integrated with address lookup functionality of LAN / Legacy E-mail systems. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I believe that the choice of a scenario will be a strategic decision for the organisation and NOT ANY TECHNICAL ISSUE. Certainly, a confidence in X.500 technology (and product chosen) is a critical factor in making this strtegic decision. In fact some discussion can be done in the direction of MERITS of each of them. In my view, Scenario-1 is a long term view of "Directory service" and Scenario-2 is a short term view of the X.500 Directory. Thanks and regards, Praveen Gupta
