Comment 7 for bug 1656772

On all controllers you can find 2 configuration values which can be described as follows:

[object_store_acces]
public_identity_ca_file = /path/to/ca/file
public_object_store_ca_file = /path/to/ca/file

Most probably these files will contain some private key as described at [0]. So, I can recommend you to copy that file, then you can remove private key from the copy. Then edit sahara configurations:

[object_store_acces]
public_identity_ca_file = /path/to/ca/file_copy
public_object_store_ca_file = /path/to/ca/file_copy

Finally restart sahara-api and sahara-engine services.
