SYSDB: Skip malformed netgroup attribute.

2015-10-11T09:13:32+00:00

It was not easy find out why netgroup could not be covert into result entries.
Problem was that nisNetgroupTriple contained unexpected string "(,user01)"
This patch will ignore only malformed attribute and processing of netgroup
will not fail.

resolv: Use the same default timeout for SRV queries as previously

2015-06-24T13:37:37+00:00

When we changed the resolver code to use the TTL values from the DNS
queries instead of harcoded ones, we changed the default value by
accident.

Add a separate SRV TTL that is backwards-compatible with the old
harcoded value.

RESOLV: Add an internal function to read TTL from a DNS packet

Adds an internal resolver function that reads the TTL for SRV records as
specified by RFC-2181. Several internal c-ares definitions are used
until c-ares contains a function that exposes all this information via a
parsing function.

IPA: Do not download or store the member attribute of host groups

2013-06-27T14:56:36+00:00

https://fedorahosted.org/sssd/ticket/1806

The IPA provider attempted to store the original value of member attribute
to the cache. That caused the memberof plugin to process the values which
was really CPU intensive.

exit original process after sssd is initialized

2013-06-25T08:42:36+00:00

https://fedorahosted.org/sssd/ticket/1357

Neither systemd or our init script use pid file as a notification
that sssd is finished initializing. They will continue starting up
next service right after the original (not daemonized) sssd process
is terminated.

If any of the responders fail to start, we will never terminate
the original process via signal and "service sssd start" will hang.
Thus we take this as an error and terminate the daemon with
a non-zero value. This will also terminate the original process
and init script or systemd will print failure.
