Hello,

I am seeing some disparity between (two distributions granted) CentOS 6.6 and Fedora22 in their use of the su utility. I cannot figure out the cause, so I cannot fix it.

In CentOS there is no way to script login to root... this is of course a desirable trait.

for instance,

[ user@localhost user ]$ su root <<EOF
> password
> echo ""
> id
> EOF
standard in must be a tty

However, Fedora22 allows this action... where is the file which I must edit to enable this security setting?
{ (^-^) user /home/user } su root <<EOF

> password
> echo ""
> id
> EOF
uid=0(root) gid=0(root) groups=0(root) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

Thanks for the help in advance.

Scott
