sssd not automatically switching to online mode when dns becomes available

[Robert Bayerl]

When using dnsmasq as a local caching nameserver, sssd does not recover if it is started
before DNS is available.

Steps to reproduce:
stop local caching nameserver
stop/start sssd
start local caching nameserver

sssd never switches to online mode or retries the DNS lookup for the SRV record.

Isn't that just a case of getting your init ordering (or dependencies
if you've something like systemd) correct, so that your DNS is started
before sssd?

That would be the workaround we are implementing, but one would think it would retry the
DNS lookup rather than just continuing to fail.

Which verison of
sssd do you use?

BTW another workaround is to send USR2 to the sssd process.
It will force sssd to reset offline state.

That's buggy version and it might explain issues.

I would recommed to upgrade to lastes 1.12 (or 1.13)
There is a ppa with sssd
https://launchpad.net/~sssd/+archive/ubuntu/updates

I didn't test whether 1.12.5 is also for precise
but there is definitely for trusty.
