Setting policies is not explicit.  You must create a policy selector through the system management console that triggers on some specific user-defined or system-defined metadata names and values.  You may also set the default policy on a subtenant to be a custom policy.  See the System Administration guide, page 192 for information on working with policies and policy selectors. [URL]
Jason Cwik    Is there an option for me to change the default policyname for the access token during the upload request in Atmos-php?   Looking at the EsuRestApi.php line 211 for createObjectOnPath function   Tried to insert following code with no luck.   $headers['x-emc-meta'] = 'policyname=SPECIALPOLICY';   Would you able to provide some light how we could achieve to change the default policyname during upload process request? Thank you.
Atmos-php set System Meta Data for PolicyName
