From the github sources
   78     { "checksum", NULL, 1, 2, 0, ARG_ON_OFF|ARG_MAGIC|BDB_CHECKSUM,
   79         bdb_cf_gen, "( OLcfgDbAt:1.16 NAME 'olcDbChecksum' "
   80             "DESC 'Enable database checksum validation' "

I tried olcDbChecksum: true, olcDbChecksum: TRUE, olcDbChecksum: 1, olcDbChecksum: ON without any success.

Do you have any ideas on how I get around this ?

Looks like the olcDbChecksum attribute is missing from the olcHdbConfig objectclass. Please file an ITS on this.
