I'm guessing you mean "and the software is fast enough", because OpenLDAP itself has been the world's fastest distributed database for over a decade, and nothing else even comes close. Since you built on top of SQLite, then you're already at least an order of magnitude slower. You could speed it up a bit by using SQLightning, which replaces SQLite's Btree engine with OpenLDAP's. https://github.com/LMDB/sqlightning https://github.com/LMDB/sqlightning But yes, it's obvious your aim is to provide bare minimum LDAP functionality for people who were only taught SQL and have no desire to learn LDAP. A bit of a loss, because the workloads LDAP is used for most often are things RDBMSs suck at.
