schurt,
Not sure what distro you are using, but I am using Redhat WS 2.1 and trying to get NIS+ working, the user can log in okay, but the /home directory is not getting automatically mounted.
1.) Make sure you do not have "medium" or "high" security firewall enabled; faster to re-install OS than undo firewall settings
2.) If using RedHat, or for some possible tips to your distro, check out:
http://www.redhat.com/mirrors/LDP/HO...WTO/index.html
3.) You have to install pam_unix2.so libraries, which are open source and included in the above document, then you have to make changes to your /etc/pam.d/login to reflect those libraries.
4.) I believe the next step involves editing /etc/auto.master, however, this is where I am stuck.
Anyway, I hope this helps you and I hope someone might be able to point me in the right direction.
