Re: DB log message (in replica server)

[Erik <edg72@home.nl>]

Jorge,

You have to be very carefull with copying BerkeleyDB files from one OpenLDAP 
server to the other when you are using the BDB backend. OpenLDAP creates and 
uses a BDB environment and you cannot just copy the *.bdb files from one BDB 
environment to the other. I do not exactly know what the meaning of the error 
message is which you see, but it could cause problems if you have to run 
db_recover on that environment. Please read the BDB documentation carefully. 
You can find it on http://www.sleepycat.com/docs. 
Anyway I advice to use slapcat/slapadd to initially sync the slave with the 
master. It is less quick, but much safer!

Regards,

Erik
