I can confirm a boot race condition (IIRC somebody talked six months ago about
autofs/systemd issues in this mailing list)

Restarting manually the sercvices in the (more or less correct) order on tjener:

1) nscd & nslcd
2) nfs-common nfs-kernel
3) autofs

Fixes WS login

I guess some careful upstream check is really needed
