sudo: don't get stuck in rules and smart refresh when offline
https://fedorahosted.org/sssd/ticket/1682
The problem was in following code:
if (ret != EOK || state->dp_error != DP_ERR_OK || state->error != EOK) {
tevent_req_error(req, ret);
return;
}
In situation when data provider error occurs (e.g. when offline),
ret == EOK but dp_error != DP_ERR_OK and we take the true branch.
This results in calling tevent_req_error(req, EOK).
Unfortunately, with EOK tevent_req_error only returns false, but
does not trigger callback and this tevent request hangs forever,
because no tevent_req_done(req) is called.
