RE: RDBMS and LDAP wars
These questions are not specific to OpenLDAP, and probably belong on the
general LDAP list @ umich.edu.
For the specific points, in general - true, false, true, false.
Referential integrity violates the normal X.500 information model, but some
servers implement it anyway.
The X.500 and LDAP protocols define a rename operation that can move
subtrees.
All directory modification operations are atomic, so transactions have no
meaning in the simple context. In the context of operations that affect
multiple objects, there is no commit/rollback support. You can create an
information management layer of your own on top of LDAP that provides this,
but generally LDAP isn't appropriate for uses that require transactional
behavior.
Reporting tools? That has nothing to do with the LDAP protocol, and
everything to do with whose application software you run.
