Synchronize user ids

Hey there!
We have several fileservers and webservers in on premises, most of them run opensuse or SLES.

What is the best way to join them to the ucs-domain while syncing the userid’s?
Our Problem is, that the users can authenticate on the servers but one user would get on each server its randomly generated user-id… so for example:

user “john” with univention-uid “10254” authenticates on fileserver and gets uid “10002”. The same user is logged in the webserver and writes a file on a mounted share of the fileserver --> and the file is written with another uid, because the user gets on the webserver its own uid…

What is the best/usual way to handle this?

Thanks for your help :slight_smile:
