NIS server delivers no passwords

Hi group,

I set up a NIS master server on my Debian Sarge (2.6 Kernel) machine to
be able to serve Kubuntu 5.10 clients with authentification.

On the server I created a new user further on called USER to test the
setup. This user does NOT exist on the client machines.

I made the required +::::... lines in: passwd, shadow, group and gshadow

Everything works fine. A "ypwhich -x" on the client gives back a list of
the maps on the NIS server. A "ypmatch USER passwd" returns the line in
the passwd file on the server which matches USER.

If I am root on the client machine I can even "su" to USER because there
is no need to type in a password (since I am root already).

I can not log in as USER, I can not change USER's password. Everything
where the client should receive the password from the NIS server fails :-(

Do you have any suggestions?

Kind regards,
Johannes

PS: I already tried a couple of things without success:

1.) changed the "compat" value in the nsswitch.conf to "files nis"

2.) tried to access the NIS server with a Debian machine (exactly same
software versions than on the server): same problem!

Problem SOLVED!
