Access Rights for Access-Token Objects
An application cannot change the access control list of an object unless the application has the rights to do so. These rights are controlled by a security descriptor in the access token for the object. For more information about security, see Access Control Model.
To get or set the security descriptor for an access token, call the GetKernelObjectSecurity and SetKernelObjectSecurity functions.
When you call the OpenProcessToken or OpenThreadToken function to get a handle to an access token, the system checks the requested access rights against the DACL in the token's security descriptor.
The following are valid access rights for access-token objects:
The DELETE, READ_CONTROL, WRITE_DAC, and WRITE_OWNER standard access rights. Access tokens do not support the SYNCHRONIZE standard access right.
The ACCESS_SYSTEM_SECURITY right to get or set the SACL in the object's security descriptor.
