I have noticed there are errors coming up when running enum4linux against a target in Kali Rolling:

============================
| Users on 10.11.1.115 |
============================
Use of uninitialized value $users in print at ./enum4linux.pl line 874.
Use of uninitialized value $users in pattern match (m//) at ./enum4linux.pl line 877.

Use of uninitialized value $users in print at ./enum4linux.pl line 888.
Use of uninitialized value $users in pattern match (m//) at ./enum4linux.pl line 890.

As well as another polenum error -- initially it says polenum.py cannot be find, and if a symlink is created to link /usr/bin/polenum to /usr/local/bin/polenum.py, then enum4linux will have the following error in Password Policy Information:

===================================================

[E] Unexpected error from polenum:
