sssctl: Showing help even when sssd not configured
On a clean and unconfigured system, it's not possible
to use --help.
1) dnf install sssd-tools
2) sssctl cache-remove --help
Shows:
[confdb_get_domains] (0x0010): No domains configured, fatal error!
Solution: Donot check for confdb initialization when sssctl 3rd
command line argument passed is '--help'.
Please note when we run 'sssctl --help' on unconfigured system
confdb check is not done and proper o/p is seen.
