NIS authontication problem.

[Hossein]

Hello every body;
	In our department we are going to use a 5.1 Stable FreeBSD, and it 
must run NIS client to authonticate the users through a Linux NIS server.
	The ypbind works well and when I do "ypcat passwd" I get the 
enteries in the passwd of the NIS server. I added the correct lines to 
passwd.master and group according to the handbook. But no user can log in 
and in the /var/log/auth.log it apears that the password is not corect. 
	The students here would be very happy to be able to use the BSD 
Shell, and I thank you in advance.

Yours,
Mohammad H. Falaki.
