Why don't you use SQLite instead??? It's pretty rock solid backend database.

Unless your client side only wants to talk LDAP.

Hi, Thanks the the response. One of the reasons for ldap is that it handles all the authentication for a lot of the packages we're using out of the box so it was a natural progression to extend it to handle the other data we need as well. The only probems, it appears, is how to make it more failsafe on the back end.

Perhaps a bit more detail... During testing our developers frequently hang the target machines. This usually results in a corrupted ldap database even though no write activity was present on the box since long before the crash.

What ldap config tuning options are required to get slapd to sync the backend to a state where power loss / kernel crashes do not corrupt the data?

Thanks

I'm working on an embedded system for which I would like to use openldap as the means of config storage. I've spent a lot of time RTFM'ing and still feel that there is a lot that is escaping me as far as the optimal configuration.

If the primary goal is data safety and zero human intervention, what would be the optimal combination of file system / backend storage / and config options?

I would like to never have to manually recover a database and have it gracefully recover from power failures. Speed is not an issue as it's very low traffic. Integritiy is everything. It's target storage is a USB flash device. Are there any special considerations WRT flash storage and ldap?

Thanks in advance.
