Unable to install wireshark on RHEL7

Issue

When attempting to install wireshark, yum install hangs during the %pre scriptlet (of wireshark) that is attempting to run:

"groupadd -r wireshark"

I suspect this is because the RHEL workstation in question is joined to our AD domain via SSSD.

For reference this is the command (until it hangs):

# yum install wireshark-gnome wireshark
Loaded plugins: langpacks, product-id, subscription-manager
...

In another terminal:

# ps -ef | grep yum
root     17565 17253  3 08:25 pts/2    00:00:05 /usr/bin/python /bin/yum install wireshark-gnome wireshark
root     18611 16686  0 08:28 pts/4    00:00:00 grep --color=auto yum
[root@cctslh15 ~]# pstree -ap 17565
yum,17565 /bin/yum install wireshark-gnome wireshark
  └─sh,17785 /var/tmp/rpm-tmp.XP61bS 1
      └─groupadd,17788 -r wireshark

Killing the "groupadd" command causes the yum operation to complete but will fail to install the wireshark RPM.
