I have a user "firstuser" that created a policy and this policy is associated to a group "sellers" with "copy", "print" and "modify" permissions.
The user "seconduser" are associated to group "sellers".
When I'm tring apply the policy by "seconduser" to a new document, the webservice throws a exception "Failed to retrieve policy [sellers] for MyPolicies -- Permission denied(error code bin: 1296, hex: 0x510);".
Can I really do this?
If you are using the "My Policies" feature, and If the user created the policy in "My Policies" then only that user (policy creator) can apply the policy to a document. These are considered "personal" policies.
You need to create a Policy Set, and then policies with in the policy set. Any user that is set as a "Document Publisher" within the policy set will have access to the policies stored in the set and can apply any of the policies to a document.
