--- Comment #5 from Quanah Gibson-Mount quanah@openldap.org --- back-bdb/hdb are gone, so those will have to be migrated to back-mdb
Existing back-mdb databases will need to be reloaded
In both of the above cases, it is probably worthwhile to document the end users should likely decide if multival should be used prior to doing the reload.
