I would like to configure remote login to CentOS 7 servers using x2go and allow multiple login with the same user i.e. many users use the same ID and password to log in at the same time.

Does x2go allow it?

I explain below a little bit more our infra :

We use NIS as user authentication We have more than 10 different Linux workstations Each colleague can connect on every workstations We use generic account for some purpose i.e. many users use the same ID and password

This is a really bad security concept. As is using NIS. And using publicly known passwords. I think you really really should rethink your setup. What's the reason you are using a setup like this?

Do you thing that this is possible to configure with x2go? If yes, what are the steps to follow? What desktop environment (MATE, XFCE, GNOME …) will be best adapted?

You can run multiple sessions with the same user. If x2go detects running sessions it will ask if you want to connect to one of those (and asks you to select the one you would like to connect to) or creates a new one.

However, there are some drawbacks:

• you will not be able to differentiate the running sessions as they are presented by just the display id. So if a colleague leaves his session and returns the next day he will (probably) not know what session to connect to to continue his work.
• most desktop environments will run into problems if started multiple times with the same user id.

As I do not recommend using a setup like this I also do not have a recommendation about what DEs are working with it. You could manipulate the server side session setup a bit in order to improve the situation by having all the sessions using different dirs for their configuration (e.g. setting different KDE_HOME variables) but it really is easier to use separate users.
