Running into "IndexError: list index out of range" exception while listing out all access info for a tenant "_DEFAULT"

[shuklanirdesh82]

Steps to reproduce:

1. make sure vmdkops_admin is running file
2. invoke following command and expect correct output
   vmdkops_admin.py tenant access ls --name _DEFAULT
3. verifies that access information comes back successfully for the tenant

Seeing following exception while invoking the command

[root@promc-2n-dhcp105-97:~] /usr/lib/vmware/vmdkops/bin/vmdkops_admin.py tenant access ls --name _DEFAULT
