Description of problem: Could it be possible in the next releases to specify several Directory Servers associated to weight or a round robin option. Like this the LDAP Client is not going to always ask to the same Directory Server all its requests even if several LDAP are defined. If it is not clear, feel free to contact me for more details.

SERVICE DISCOVERY The service discovery feature allows back ends to automatically find the appropriate servers to connect to using a special DNS query. Configuration If no servers are specified, the back end automatically uses service discovery to try to find a server. Optionally, the user may choose to use both fixed server addresses and service discovery by inserting a special keyword, “_srv_”, in the list of servers. The order of preference is maintained. This feature is useful if, for example, the user prefers to use service discovery whenever possible, and fall back to a specific server when no servers can be discovered using DNS. The domain name Please refer to the “dns_discovery_domain” parameter in the sssd.conf(5) manual page for more defails. dns_discovery_domain (string) If service discovery is used in the back end, specifies the domain part of the service discovery DNS query. Default: Use the domain part of machine´s hostname The protocol The queries usually specify _tcp as the protocol. Exceptions are documented in respective option description. See Also For more information on the service discovery mechanism, refer to RFC 2782. When using DNS discovery, RFC 2782 specifies a weighted round-robin approach. So to accomplish what you're asking for, it can already be done simply by setting SSSD to use DNS SRV records as described above, and configuring the SRV records on your DNS server according to RFC 2782.
Well, you are perfectly right. I did not think about that. Well done ! BR Frederic ;)
