I have pulled the sources that had the fix from the git repository and reco=
mpiled openldap. Following the patch, config creation worked fine.

To verify that it is working as expected, I tested with the olcDbChecksum s=
et to true/false and verified the checksum flag of the database created as =
per below output.

For both BDB/HDB backends, olcDbChecksum set to true, removed all files und=
er /var/lib/ldap/*  and started server to re-create database.

[root@host01 ldap]# db_dump /var/lib/ldap/dn2id.bdb=20
VERSION=3D3
format=3Dbytevalue
type=3Dbtree
chksum=3D1
duplicates=3D1
dupsort=3D1
db_pagesize=3D4096
HEADER=3DEND
DATA=3DEND
[root@host01 ldap]#=20

For both BDB/HDB backends, olcDbChecksum set to false, removed all files un=
der /var/lib/ldap/*  and started server to re-create database.

[root@host01 ldap]# db_dump /var/lib/ldap/dn2id.bdb=20
VERSION=3D3
format=3Dbytevalue
type=3Dbtree
duplicates=3D1
dupsort=3D1
db_pagesize=3D4096
HEADER=3DEND
DATA=3DEND
[root@host01 ldap]#=20

>From the output above, it is working as expected. Thanks for your prompt su=
pport and patch.
