Hello. I am logged in as administrator, open administration -> users, but can't find the "lock permanently" button as described in the documentation. 
Maybe some setting?  p.s. OP the latest (docker).

Thank you

Hello, please share a full screenshot of administrator, open administration -> users

please share your exact OS and Version and Browser and share which of the many docker versions you use... at the moment your information could be more detailed

I run OpenProject docker compose 12.3.2 on Ubuntu 22.04 in Firefox 106 with external apache webserver 

Thank you

I think you must adjust the screen resolution, maybe the Lock permanently is not displayed?

OP 12.3.2 is installed a few days ago.
Server OS - Centos 7.9
Client's browser -FF 105

I have access to the server shell, what else information can I provide?

Thank you!

Maybe it's because the user is not activated? I didn't find such a button either :(

>Maybe it's because the user is not activated?
Yes, that was the reason  :-)
Activated the user by changing the password and the button appeared. 
Thank everyone for your help!

Hi Yuri

The first initial admin user in the cloud cannot be deactivated via GUI, if you would like to have a different admin user, then we can solve this, too and deactivate the first admin user... but i understand that you solved he riddle for your case, congratulations. You are very welcome
