Wow! It worked! I didn't have to 'weaken' the security of my
system. Tramp is truly wonderful.
Only one odd thing - even though I'd already established a tramp
session as:
/su:otheruser@localhost:
When I opened my first buffer using "C-x C-f /sudo:root@localhost:"
(from an active buffer 'owned' by otheruser) it seemed to ask for
otheruser's password again, i.e. it first asked for a password for
/su:otheruser@localhost: and then it asked for a password for:
/sudo:root@localhost:
So in total I ended up entering the password for otheruser 3 times -
it seems like my first tramp session as 'otheruser' did not get
"reused". I presume the above is because of the proxy also getting a
tramp session?
Thank you and regards,
Jonathan.
