I noticed that it took quite a long time till the client had 'learned' that there was a password change. I didn't notice this until I tried to login again after a coupe of hours and suddenly the old password didn't work anymore but the new one (I supposed I had set it to) didn't work either. So I changed it back on the server side, did a make in /var/yp and immediately after that the freshly set password let me successfully login on the client. These effect may seem boring - I know. I will go back and make sure that everything is in sync and try to UTSL as much as I can. > > Is libcrypt the same on all machines?
