Is it possible to use Syspass with memcached as a session handler?

[hostings-vpt]

sysPass Version Syspass 3.2

Describe the question Is it possible to use Syspass with memcached as a session handler?

Platform (please complete the following information):

• OS: Linux
• OS Version: Debian 10 (Docker image - syspass/syspass:latest)
• Browser: Any

Additional context We have been trying to implement memcached as a session handler for Syspass because we are using Docker as the platform for the application to be able to scale up in the cloud when needed and we haven't been successful. When making requests to the homepage, a 'Session cannot be initialized' error is displayed. Logs in syspass.log say:

2021-07-20 10:34:13] syspass.ERROR: logger {"message":"Could not set locale","caller":"SP\Core\Language::setLocales"}

Here is our memcached configuration on php.ini:

session.save_handler=memcached
session.save_path=<AWS_MEMCACHED_PATH>
memcached.sess_prefix="syspass_memc.sess.key."

Any help on this issue would be useful.

@hostings-vpt Just came across same issue. Seems they override default memcache settings from ini inside APP. When I force this in FPM pool settings. The error goes away and sessions works.

php_admin_value[session.save_handler] = memcached
php_admin_value[session.save_path] = "127.0.0.1:11211"
