I have identified a problem and still have no solution.
But maybe someone has the same problem.
I use the ubuntu laptops and computers in versions 19.10 and 20.04, the clients are integrated into my domain.
(I set it up with the following HowTo)
I have now changed my password in the cockpit, but it has been accepted, but the clients do not synchronize.
With a laptop I can log in with the new password, on two other computers only with the old password.
Who knows the problem, how can I reconcile the passwords?
