Hi Fabrizio and Andreas, The stat request already tells you whether the file is readable or writable. In the xrootd world information beyond that is somewhat ephemeral as the server owns all the files and access permissions do not fit into the normal Unix framework. I say that because access persmissions are determined by the authorization plugin (or in Alice's case, the filesystem plugin). So, permissions are relative to the person making the request and can only be represented externally by a yes/no indication. The chmod was put in strictly to control overall read or read/write access for everyone and really wasn't meant to be useful in the "Unix" way. Chown was never put in since it didn't make any sense. It's important to realize that xroot does not present a traditional filesystem and will never be able to do so (well, at least not without sacrificing performance).
