Title
Domain Users Using Cached Credentials To Log in To Ubuntu -
Description
After rebooting Ubuntu 16.4 if a domain user logs in immediately they are logged in using cached credentials. It takes about 60 seconds before they are successfully logged on to the domain.
If the users’ credentials are not cached on the computer then they will get an “Invalid password” message.
-
Cause
The network isn’t fully up when Authentication Services (AS) tries to talk to Active Directory (AD). So AS marks servers as unreachable for one minute and then looping back to check them again. The network is up about 2 seconds after AS marks the servers as unreachable.

Resolution
On the Ubuntu computer
- Open the following file in a text editor.
/lib/systemd/system/vasd.service
- Add the lines:
After=network-online.target
Wants=network-online.target- Save and exit
