Iíve configured my arm64 instance with:
dn: cn=config
olcIndexHash64: FALSE

The indexes are still broken though, is this the configuration youíre referring to? Given my mdb is from an amd64 box, itíll be 32 bit, so I want to match the configuration.

I just checked on a local box. My ARM64 build defaulted to 64bit index keys, the AMD64 build used 32bit index keys. Not sure why the defaults are different,
but configuring 64bit index keys on the AMD64 box would fix this.
