30.6.2. Using SRV Records with Failover

PDF

SSSD supports SRV records in its failover configuration. The SSSD configuration can specify a server that is later resolved into a list of specific servers using SRV requests.

For every service with which to use service discovery, add a special DNS record to the DNS server:

_service._protocol._domain TTL priority weight port hostname

The priority and weight attributes of SRV records provide fine-grained control over which servers to contact first if the primary server fails.

A typical configuration contains multiple such records, each with a different priority for failover and different weights for load balancing.

For more information on SRV records, see RFC 2782.
