During testing of HA clusters some time ago I found BDB to always be the 
first thing to break. It seems to have very poor recovery and seems not 
fine with neither file systems snapshots nor power failures. 
Nevertheless it's claimed ACID conform. I don't know -- from my 
experience I wouldn't even put my address book on it.

Personally I ended up doing this for OpenLDAP and never looked back:
