justemail, I must confess I don't know what the /- does in the auto.master file, but I would be interrested in trying to change it to something like /tib so it reads
Then try auto.tib puting this in auto.tib
/etc/auto.tib looks like this:
html -rw,fsid=0,sync,hard,intr ds1:/var/www/html
A "cd /tib/html" is what I'm suggesting as a try. If you can mount manually I'd assume nfs is fine.
Also, tail your /var/log/messages file on both systems to see if anything obvious shows up.
Other things that come to mind:
1) did you restart the autofs service?
2) rs1 does not already have a /var/www/html directory.
Keep us updated, I'm curious as to what this is and to learn what /- does.
