slapd, bdb, 32-bit -> 64-bit

[Frode Nordahl <frode@nordahl.net>]

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.

We are running OpenLDAP in a distributed environment where every  
server has a local copy of the LDAP database for performance and  
reliability reasons. The database is 6 GB, so it is non-trivial  
export it to LDIF and import it again on the 64-bit systems. (It  
takes way too long).

I am setting up one server to just be a spare LDAP slave so we  
easilly can take it down and copy the database to any new system  
added to the cluster without causing any downtime anywhere. But this  
is not possible as long as I cannot use the same database on 32-bit  
and 64-bit systems.

Would it be possible to make this work at all?

Could this be caused by a platform-dependent variable type being used  
somewhere, rather than a fixed sized variable type, making slapd  
interpret the same data diffrently on different platforms?
