If an object can't be resolved as a posix group we then try to resolve
it as a non-posix (without the gid attribute) nested group and store it as a
group stub into the sysdb.
The purpose is to be able to resolve nested posix groups which are
members of non-posix groups.

This reverts commit fc8d98c9f0bb26de7be732c3e542b85c8abdba53.
The reason why the control was marked critical is that we expect
to get it back on reply, or it should fail. We should rather leave
the criticality bit and handle the error (by downgrading to not use
deref controls) if the server fails.
In other words, we should not workaround bugs in any LDAP server.
If server claim it support deref control, it should work with critical flag.

apply_subdomain_homedir() didn't handle the situation where an entity
that doesn't match was requested from the cache. For user and group
lookups this wasn't a problem because the negative match was caught
sooner.
But SID lookups can match either user or group. When a group SID was
requested, the preceding LDAP request matched the SID and stored the
group in the cache. Then apply_subdomain_homedir() only tried to search
user by SID, didn't find the entry and accessed a NULL pointer.
A simple reproducer is:
$ python
>>> import pysss_nss_idmap
>>> pysss_nss_idmap.getnamebysid(group_sid)
The group_sid can be anything, including Domain Users (XXX-513)

With this path, a user whose name is "space user" would match a sudo
rule while using the override_default_space option. Please note that the
option is only a client-side override, so the sudoUser attribute must
contain the space in order to match the original name. In other words,
when substituting space ( ) for underscore (_), this attribute would match:
sudoUser: space user
this would not:
sudoUser: space_user

The meta server status consists of two parts:
A) port status - managed by failover mechanism
B) SRV lookup status - managed by SRV resolver
Both parts are resetted to "neutral" after some time, having
B timeout greater than A timeout.
We were hitting the following issue:
1. SRV lookup fails (DNS is not reachable), this will set A to
"not working and B to "resolve error". Then the next server is
tried but fails as well.
2. If SSSD tries to go back online the failover will set A to
"neutral" and it will try to resolve SRV again. But B status is
still set to "resolve error" since we haven't reached the timeout
yet and SRV resolution fails immediately. But the next server
is not tried since the port status (A) remains "neutral".
This patch sets the port status to "not working" making the
failover to continue with the next server as expected.

This patch adds periodic check to test if
backend can exit offline mode and only
marks backend as not offline if server
for the service is available.
Prior to this patch we marked backend as not
offline if the offline_timeout was reached
without checking for the server availability
and when the next request failed again
we switched back to the offline mode.
This caused significant slowdowns in some
edge cases.
