Hi, I am trying to install NextCloud 14. I have 2 apache HTTP servers and 1 database (master-slave replication with Galera). I installed NC on the 2 nodes, pointing to the same database and all went right. I have issues when I log in the first server. The users I create/update on the 2nd server are not usable on the first (bad credentials). I guess there must use the same key on the 2 servers to cipher the passwords, but I can’t find how to setup this. Please help ! Ben ---

@JasonBayton don’t YOU run a cluster of NCs already? so perhaps you would have some hints for those guys? 😉 ---

I vaguely recall this may have been due to session storage. @nickvergessen gave me a tip on that I then used to get everything working! ---

This may be a VERY stupid question, but in your `config.php` file, does the `instance_id` parameter differ? We saw some funky stuff too, and once we made sure that the `config.php` files were exact matches (only changing the trusted domain parameter to the individual servers) it seemed to solve a lot of things for us. ---

I have this in my config.php ```auto 'memcache.distributed' => '\\OC\\Memcache\\Redis', 'memcache.locking' => '\\OC\\Memcache\\Redis', 'filelocking.ttl' => 3600, 'filelocking.enabled' => 'true', 'memcache.local' => '\\OC\\Memcache\\APCu', 'redis' => array ( 'host' => 'IP_of_Redis_Server', 'port' => 6379, ), ``` Note the `memcache.distritbuted` variable, and that I use APCu for local memcache. I should note to you that we use LDAP for user provisioning, so not sure how local user provisioning would work. We have no issues atm regarding your symptoms, but as I said, we use LDAP. ---

I tried to create the following configuration: ![](https://help.nextcloud.com/uploads/default/original/2X/b/b9a67414e53b780ee50560b2e9ff33a854c211c9.png) The original setup was data, database and nc on a single server (NC1). Now a second server NC2 is running in parallel using the database and data (SMB mount). The config.php on the servers is near identical (in particular, instance\_id, password\_salt, secret, database, data). No distributed cache. Currently, DNS announces NC1 to be the ‘cloud’. For testing, a local DNS override makes it possible to use NC2 as cloud on a single PC only. Problem: I can login to NC2 and everything works. Logging in to NC1 gives username/password incorrect. I can request a password reset, change the password to its original value, and login to NC1, once. And then the username/password is incorrect again. NC2 continues to work with the same credentials as always. All other clients on the network that use NC1 (with the same credentials as always) stopped working. I must be overlooking something… But what? ---
