I've got a server running CentOS 5.2 and has a working NFSv4 server. I've been looking for some help on this on the net, but haven't come across anything that looks like it would pertain to my situation.
Basically, I've got a mixed distro environment (CentOS, Fedora, openSuSE, Ubuntu, Puppy, and yikes possibly a Windows box) on various desktops and laptops that I want to connect to my server. Currently, I've got it setup so that it is only NFSv4 with a host mask. My first concern is that it authenticates to the machine, not the user. Second, that the user is identifed by the UID on the local machine, not the actual user name. Since Centos/Fedora start UID at 500 and Ubuntu/opensuse start at 1000, even though the names are the same, UID is not. I'd rather not have to reID on half my machines Third, I know I'll need samba for the windows box. So, if someone were to get on my local network and have the same uid as I have, then they could mount my shares as rw and have at it.
The ideal situation is that a user would logon to a local box, then when he wants to access a share, it sends the credentials to the server, and mounts the share. This is all for my home setup; basically, I'd like to have my directories be mounted rw for myself, but if i have guests over, have them be able to mount read only (sharing pictures with family memebers that have laptops, etc).
Thanks, Ryan
