Hello, I am trying to use a slapd BDB database created on a 32-bit intel system on a 64-bit (amd64/EMT64) system. Running slapcat on the database works fine, but when the server is started, ldapsearch is unable to find anything. I understand that there are architectural differences between a 32- bit and 64-bit systems, but I don't think Berkeley DB have any problems with having its data being interchanged between the platforms.
No, this won't work. On a 64 bit build the entryIDs in the database are 64 bits. You must export to LDIF and re-import the DB.
Thank you for your reply!
I spent a lot of time thinking over this decision; whether to keep entryIDs 32 bits wide for 64 bit builds. Ultimately I decided that 64 bits was better. We have a deployment that has upwards of 3 billion entries, and they add/delete millions of entries per day, so restricting things to only 4 billion entryIDs would have been too much of a restriction.
I think you made a wise decision. 5-10 years from now most servers will have been replaced by newer systems capable of running 64-bit operating systems, and this will be a thing of the past.
