OpenSuSE 12.1 NIS users are unable to login until both ypserv and ypbind are restarted.

After rebooting the system NIS users are unable to login.

  1. Both ypserv and ypbind are running
  2. getent passwd username returns nothing

solution (ugly #1)

  1. login as root and restart ypserv and ypbind

solution (ugly #2)

  1. open NIS client configuration in yast and save it

Is there a way to verify what is wrong?

solution (ugly #3)

Use a traditional ifup for the network instead of networkmanager, however network interfaces are initialized with network manager even neither of the users logged in into the system. Not having a network manager for laptops doesn’t make any practical sense.
