Hi All.

I am trying to install some software. Part of its installation is an
invocation of command similar to:

# sudo  -H -E -u postgres /bin/bash -c /usr/bin/python2.7
/bin/bash: /usr/bin/python2.7: Permission denied

>From my perspective:
# ls -l /bin/bash /usr/bin/python2.7
-rwxr-xr-x. 1 root root 960376 Jul  8  2015 /bin/bash
-rwxr-xr-x. 1 root root   7136 Oct 11  2015 /usr/bin/python2.7

# su - postgres

I tried the same for /bin/top. From my perspective this is quite a strange
behaviour. Can someone help with this problem?

BR,
Rafal.
