I pretty much understand how permissions work on a single system basis, but I'm having difficulty understanding how they work across two machines.
If i go to \\192.168.3.19 (the servers IP) and login as 'smusr' with my password,
I can read and write without a problem, since 'smbusr' a user on the server is a member of the 'web1' group, and the files are set to 575.
This is where it get's weird: If I mount the share \\192.168.3.19\web at /web on my local machine, using 'smbusr' and the password, it mounts, but does so as read only. Even though that user does have write access as far as the server is concerned. It seems like my desktop computer is trying to add permissions on top of a network resource that already has permissions.
