Network user accounts not displaying on log in screen 2

Hi,

Following this thread Network user accounts not displaying on l… - Apple Community

The answer doesn't work for me.

Attempts :

• I tried both AD servers for Prefer this domain server.
• I tried with mobile account enabled.

When I'm logged with local admin account, (then only one at first login), System Preferences / Users & Groups / Login options shows the domain joined. But the option (translated from french) Enable to network users to login to the opening session window is not displayed after few seconds. I don't know if it es relevant.

Context :

• AD WS2012R2
• macOS Mojave 6
• authentication and contacts checks enable for AD.
