Description of problem:
When attempting to use Emacs's gnuserv/gnuclient in conjunction with su,
pam_xauth does not copy the :999 xauth cookie, rendering gnuclient unuseable by
root (or whatever other account is su'd to).
Steps to Reproduce:
1. Start Emacs/XEmacs
2. Do M-x gnuserv-start
3. From command-line, do:
$ gnuclient -batch -eval '(princ "Hello world")'
4. Should get an output in the *Messages* buffer on XEmacs (or equiv
$ su -c "gnuclient -batch -eval '(princ \"Hello world\")'"
gnuclient: Connection refused
gnuclient: unable to connect to remote
Should get and output in the *Messages* buffer (or Emacs equiv), as in 4.
Is this bug still in the latest Fedora Core?
Yes, this bug is still there. xauth_pam only copies the cookie
associated with DISPLAY, but doesn't copy the 999 cookie, which is
required for proper gnuserv/gnuclient operation.
I do not plan to work on this problem any time soon. Please reopen if you have patch.
