We are developing our IRM client. We need to show some related information about the protected document such as "Offline Duration" and "Expiration Date". However, the client integration api provide no such function, instead we find the server management api does provide some related functions such as PVS_PolicyGetExpireAbsolute and PVS_PolicyGetMaxLease. The problem is both of them require the supply of policy object (PVS_Policy_t policy). To get this policy object we can use a function PVS_DocPolicyLoad also from the server management api, but we find that only user login as doucment owner can get this policy object. Therefore, other users cannot check those information for the protected document. We check about Microsoft Office, users other than owner are also able to check these information. So, how can we allow users other than owner to check information such as "Offline Duration" and "Expiration Date" for protected documents?
