LDAP vs. DBMS (or migrating to fedora directory server)
Via the Fedora Miniconf, I attended Del Elson’s talk on Migrating to Fedora Directory Server. Interesting scripts, and glue code was presented, the slides (verbose, good) are online, but there’s no video :(
Tiny amount of notes:
LDAP vs. DBMS
- directory has one schema, one “row” type (”object”). RDBMS has many tables
- directory => optimised for reads, slow for writes
- directory has an adaptable and mutable schema format - good for storing information about “people”
- think about the fact, that people usually have more than one phone number…
- access protocol - ldap vs. sql

It’s a pity it’s got some inaccuracies about OpenLDAP. Let’s see - it does multimaster in 2.4, has done schema replication since 2.3 (as part of in-directory config replication - FDS doesn’t do that). And there’s no mention of benchmarks. Admittedly I’m in the camp that can’t understand why RH bought NDS instead of contributing to OpenLDAP - sure, I’ve got nostalgia for the Netscape server products, but that doesn’t make them good code.

@James: Yeah, totally agree.
Shame they won’t even use their own software:
