Also FreeRadius (if your app's support Radius and LDAP) supports a myriad of backend databases.
Hmm, very interesting. I was not aware of this project. My concern is that there's been very little activity on the project in recent years.
Is there no simple, reliable, backend config for openldap?
I'm not concerned with speed, just reliability and data integrity.
I'd settle for a 10x performance penalty for data integrity.
You could give back-ldif a try. It certainly will not perform well, but it's so simple that data corruption wouldn't be an issue.
I'll give it a try. Thanks.
Are there no hdb back end settings that accomplish something similar ? Or is that back end always going to be vulnerable to ungraceful shut downs?
Thanks

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
