somehow I turn stupid again.
My problem is secondary not a direct Nethserverproblem but a mixture of several.
Problem is the inclusion of releases using pam_mount in the client, my clients use xubuntu.
If the computer is connected to the LAN cabel the integration of shares works wonderfully, as soon as I use a WLAN connection, it is no longer possible.
Problem is that when I log in with the domain user, the wireless connection is first capped and rebuilt after logging in. However, mount with pam_mount will stop working.
Is it possible to integrate the domain users in a local group on the client that the use of the wireless network is regulated there.
Before logging in I tested the WLAN connection in the console - it works.
