[gentoo-dev] yp/nis problems

Hello

I have been experimenting with gentoo for the last 2 weeks
(complete feedback may follow if wanted) but now I have run
into serious problems:

I need to integrate the gentoo-machine into a yp/nis surrounding
which is using neither md5 nor shadow passwords.
ypwhich, ypcat -k passwd and getent passwd work allright
even C-calls to  yield the right answer.

But I can't login/ssh into the machine as a non-local user.
In the syslogd I just get 'Failed password for...' and
'Failed keyboard-interactive for...'-entries.

This may be pam-related but our RedHat 6.2-Boxes using
a similar pam-setup work fine.

So has anyone already successfully set yp/nis & has some hints for me?

Many thanks in advance!
