I can't make a generic function, the ldap backend uses URIs like ldap://foo.bar:123, ldaps://bar.baz While the IPa backend uses a list of fqdns: fo.bar.baz, foo2.bar.baz So each backend has to init on it's own based on the syntax it uses. > > A set of callbacks is made available so that if a new resolution is > > performed that changes the server currently in use then all providers > > can update their status. > > > > I have done limited testing with the ipa backend which exercises both > > the ldap and krb code, although the standalone krb code still doesn't > > implement using the failover code. > > > > Simo. > > > > I have tested with with three server and can see that they are tried one > after the other, but if the last one is reached and fails it looks like > it never tries other servers again.

Although I also have seen a longer dealy than I expect this should start working after a few tries, when the failover code decides the blackout for a specific server is over. If that doesn't happen we need a patch for the failover code I think.
