Ok, here is the deal. I have 2 laptops and 1 server. I just rebuilt one of the laptops from scratch. All systems are running Ubuntu 12.04. Before the rebuild, if I performed the command ls -l, the owner and group names matched correctly when I was on any machine.
Now that only works on the server and one laptop. The one I just rebuilt, well it shows all files in the NFS folders as nobody nogroup.
I checked and my UID and GID are the same on all computers.
I am not using LDAP, I am synchronizing the UID/GID by hand from the command line.
When I do "ls -ln" to get the numeric UID/GID, the server of course is correct but the rebuilt laptop shows weird numbers that make no sense.
It gets even stranger. If I create a file on my laptop in the NFS folder, then "ls -ln" the numbers are wrong. But on the server, they are right!!!!! What the heck?
On my all computers, my UID and GID are 1000 and 1000.
I think the mapping between users is all messed up but I can't figure out what to look for.
Any help would be greatly appreciated.
