New servers that are installed with dogtag 10 instances will use a single database instance for dogtag and IPA, albeit with different suffixes. Dogtag will communicate with the instance through a database user with permissions to modify the dogtag suffix only. This user will authenticate using client auth using the subsystem cert for the instance. This patch includes changes to allow the creation of masters and clones with single ds instances.
