IPA doesn't officially support RFC 2307 IP services. However SSSD has a nsswitch plugin to provide service lookups. The subtree search for (&(ipserviceport=$PORT)(ipserviceprotocol=$SRV)(objectclass=ipservice)) in cn=accounts,$SUFFIX has caused performance issues on large installations. This patch introduced a dedicated container cn=ipservices,cn=accounts,$SUFFIX for IP services for future use or 3rd party extensions. SSSD will be change its search base in an upcoming release, too. A new ipServicePort index is added to optimize searches for an IP service by port. There is no index on ipServiceProtocol because the index would have poor selectivity. An ipService entry has either 'tcp' or 'udp' as protocol. Fixes: https://pagure.io/freeipa/issue/7797 See: https://pagure.io/freeipa/issue/7786 Signed-off-by: Christian Heimes <cheimes@redhat.com>
