Login loop when php session are saved in memcache : Current user is not logged in

ℹ️ Support
1

Hello

Nextcloud version : 18.0.3 but I have exactly the same problem with v 17
Operating system and version : deb10
Apache version : apache2.4.38-3
PHP fpm version : 7.3.14-1~deb10u1
php-memcached : 3.1.3+2.2.0-1
memcache : 1.5.6-1.1

The issue you are facing:
When i try to enable session save in memcached in php.ini nextcloud break.
The first login is success full but then there is a login loop
If i disable session save everything work as expected

php.ini:

session.save_handler = memcached
session.save_path = '127.0.0.1:11211'

When I test memcache everything theems to work as expected (a php script to test session save is working correctly) :
number of visits: 12 Server IP: 192.168.x.10 Client IP: 192.168.x.22 Array ( [PHPSESSID] => djclotqr5jio0cjoc1mflpjduj )

If i clean my browser cache first login work then not.

Is this the first time you’ve seen this error? yes

Steps to replicate it:

  1. activate session save in memcache (/etc/php/7.3/fpm/php.ini)
  2. first login work
  3. the login loop with error Current user is not logged in

As far as I understoodd this option is not really supported. Please see the following discussion about it:

This should be supported.
If you need HA, how can you share php session between two (and more) server if you cannot use redis or memcache?

If you have an other website with php session in memcache, you can’t host them together???
