Bug#235804: gksu: problem with pam_wheel.so trust group=adm

[Edward J. Shornock]

Package: gksu
Version: 1.0.4-1
Severity: normal
Followup-For: Bug #235804

For awhile now, gksu would hang after inputting root's password, yet the
process would still be running.

/etc/pam.d/su  contains:
uth        requisite   pam_wheel.so group=wheel debug
auth       sufficient pam_wheel.so trust group=adm

Creating a new user, I just added them to the wheel group but NOT to the
adm group.  gksu worked as intended.  After I removed my username from
the adm group, I could use gksu as well.  Now I just need to input
root's password when running "su".

I don't know if this will help, or if it's a problem with the gksu
package, but here's the output from the strace of the process, after
putting in my password (and after changing my real password to
"mypassword"):

read(3, "\1\0\17\2\0\0\0\0L\27 \1\0\0\0\0\1\0\0\0\1\0\0\0H\223Y"..., 32)
= 32
ioctl(3, FIONREAD, [0])                 = 0
poll([{fd=3, events=POLLIN}], 1, 0)     = 0
write(4, "mypassword\n", 7)                 = 7
waitpid(21936, 0xbffff6ac, WNOHANG)     = 0
select(5, [4], NULL, NULL, {0, 100})    = 1 (in [4], left {0, 1000})
read(4, "mypassword\r\n", 255)              = 8
waitpid(21936, 0xbffff6ac, WNOHANG)     = 0
select(5, [4], NULL, NULL, {0, 100})    = 0 (Timeout)

So now gksu works fine for me. :)  Hopefully this will help someone else
out as well...
