Tool requires access to operation system where VPLEX is running.
Note access to vplexcli is not needed.

There is probably change in default behavior between version VPLEX 5 and 6.

When you create user in VPLEX 5 then you gets direct access to operating system prompt.
VPLEX 6 startes vplexcli immediatelly after login via ssh.


Right access via ssh:

$ ssh xormon@VPLEX01_host
  Last login: Fri Sep  8 06:54:20 2017 from 10.1.1.1
xormon@VPLEX01:~> uname -a
  Linux VPLEX01 3.0.76-0.11-default #1 SMP Fri Jun 14 08:21:43 UTC 2013 (ccab990) x86_64 x86_64 x86_64 GNU/Linux

Wrong access:

$ ssh xormon@VPLEX01_host
  Last login: Fri Sep  8 06:54:20 2017 from 10.1.1.1

How to fix it?
There could be done some workaround as far as we know.
We got no details, perhaps removal of starting vplexcli from .profile or .bashrc ...
