Can you test this plugin out for both ds7 and 8:

class ds(sos.plugintools.PluginBase):
    """Directory Server information
    """

    ds_version = None

    def checkenabled(self):
        if self.cInfo["policy"].pkgByName("redhat-ds-base") or os.path.exists("/etc/dirsrv"):
            self.ds_version = "ds8"
            return True
        elif self.cInfo["policy"].pkgByName("redhat-ds-7") or os.path.exists("/opt/redhat-ds"):
            self.ds_version = "ds7"
            return True
        return False

    def setup(self):
        if "ds8" in self.ds_version:
            self.addCopySpec("/etc/dirsrv/slapd*")
            self.addCopySpec("/var/log/dirsrv/*")
        if "ds7" in self.ds_version:
            self.addCopySpec("/opt/redhat-ds/slapd-*/config")
            self.addCopySpec("/opt/redhat-ds/slapd-*/logs")
        return

Test the ds and cs plugins in the upstream version :

http://astokes.fedorapeople.org/sos-1.8-9.noarch.rpm

They'll be backported to RHEL if works for you.

Thanks,
