Anyone have any pointers on where I can find more information on this?<o:p></o:p> <o:p> </o:p> In particular, I’m struggling with whether to use a directory server for user management or a database. If I store users in my LDAP directory (e.g. username, password, name, address, phone, etc.), there is still user data that I need to store in a database (e.g. transaction data or other frequently modified data) … and I need to be able to correlate the two. For example, for reporting I may need to display both the basic user info and demographic information that is so well suited for a directory alongside data that comes from a database. This seems to me problematic since the data models and query languages are different. And even if I could make the LDAP data look like something I could query with SQL … and join with real RDBMS tables … it would seem likely that performance might be less than great.<o:p></o:p> <o:p> </o:p> My thinking is that if I could get the LDAP server to use e.g. MySQL under the covers for storage, but I could still get access (read-only) to the underlying tables, I might be able to have the best of both worlds (assuming the underlying table structure was amenable to being joined to my tables without to many contortions). I’m guessing my dilemma isn’t new … has anyone else struggled with this and, if so, how did you resolve it? And have been satisfied with the solution you selected?<o:p></o:p> Thanks for any input or comments.<o:p></o:p> <o:p> </o:p> Bill Bailey<o:p></o:p> <o:p> </o:p> </div> </body> </html>
