curl: (77) Problem with the SSL CA cert (path? access rights?)

[jpari...@gmail.com]

On executing below command:

curl --cacert $PWD/cluster.crt --cert $PWD/user.crt --key $PWD/user.key https://<IP address of the Flocker control service>:4523/v1/configuration/containers

getting an error:
curl: (77) Problem with the SSL CA cert (path? access rights?)

I have provided the required permissions on the /etc/flocker directory.
Also, required authentication certificates are generated and copied to /etc/flocker directory.
