MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Otherwise pam can use the changed information whe id chaching is
enabled, so next authentication that fits into the id timeout
(5 seconds by default) will still sees the password as expired.

read/write/check helpers.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
It's kind of expected that in case `(POLLERR | POLLHUP | POLLNVAL)`
error condition is detected, regular `POLLIN/POLLOUT` won't be set.
Error code set by error condition should have a priority. This enables
users of this helper to retry attempt (as designed).

Fixes an issue when the sssctl analyzer option is
used on systems where SSSD is not running or configured. This is
an expected use case when using --logdir option to analyze external
log files.

Subject: [PATCH 9/9] Analyzer: support parallel requests parsing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Analyzer code(primarily the list verbose command) needs
changes to handle parsing the necessary lines from
NSS/PAM log files when multiple intermixed/parallel
client requests are sent to SSSD.
Resolves: https://github.com/SSSD/sssd/issues/6307

Subject: [PATCH] CLIENT: fix client fd leak
- close client socket at thread exit
- only build lock-free client support if libc has required
functionality for a proper cleanup
- use proper mechanisms to init lock_mode only once
:relnote:Lock-free client support will be only built if libc
provides `pthread_key_create()` and `pthread_once()`. For glibc
this means version 2.34+
