Can an asset or asset group be requested via a password access request policy?
No, assets and asset groups can only be requested via an RDP access request policy.
Password access request policies are intended only for accounts/account groups. It is not possible to add assets/asset groups to a password access request policy from the entitlement settings, however it is possible to add them from the asset's Access Request Policies tab.
Even if an asset or asset group is added to a password access request policy, they do not show up as an option to be requested.
The access request dialog populates first according to the policy type then second with the policy scope. So if the policy type is password, all assets will be ignored even if they are within the policy scope.
In the event the access request policy's type is changed to RDP, then it will populate with assets along with accounts.
