The same argument came up in a big company, incidentally for the same use case, certificate store in a CA. This led to benchmarks, where OpenLDAP was significantly slower, like three orders of magnitudes. Databases have gotten really faster in the last couple of years while OpenLDAP has stagnated.

Got a link to a report on that?

OpenLDAP serves queries at line rate on multi-gigabit NICs, with latencies indistinguishable from ping RTTs. Other databases aren't even close.

InnoDB is a bloated pig. No, it hasn't gotten 5 orders of magnitude faster in the past 10 years. http://www.lmdb.tech/bench/memcache/

And the overhead of SQL processing vs LDAP protocol hasn't improved any either.

You're spouting lies.

Still completely sufficient for the workload, apparently.

Wouldn't need to upgrade server hardware as often...

Would their needs be met by a simple key-value store?
