The main control is to check '/etc/nsswitch.conf', verify that you have something like : 'passwd: files nis systemd'.
In this situation, all tests must be done in 'console' mode to debug, not with a window manager - you can stop the window manager.
About the 'homedir', local to the Linux (Debian) machine or NFS ? If it's NFS, verify the rights to the homedir.
What's happen if on the Linux machine you are logged as 'root' and make 'su - test' ? An other test, use an other local account, as 'root' and make 'su - <the other account>', and after 'su - test'. If you haven't restricted the root's rights, this a good way to check the password.
During this, in your a console (I use 'tmux' in this case), make some 'tail -F /var/log/< ...>' to find where the password could be rejected.
Some files to observe in '/var/log' : auth.log, kern.log
Update : I suppose that your are working on the same domain name. If you have 'host_one' and 'host_two', the corresponding FQDN is 'host_one.your_domain' and 'host_two.your_domain'. I don't know how works the NIS service if the machines are not in the same domain name.
