Embodiments are directed to managing data in a file system. A file system engine may provide a file system that includes file system objects accessible by two or more clients that use different native permission schemes. The file system engine may receive an access request from a client to access the file system objects that includes native permission values. A permissions engine provides platform permission values from a platform permission scheme associated with the file system objects. The permissions engine provides requested platform permission values based on the platform permission scheme and the native permission values included in the access request. The permissions engine compares the requested platform permission values to the platform permission values associated with the file system objects. The permissions engine provides access rights to the file system objects based on an affirmative result of the comparison.
