I have a NFS storage where I want to create and modify files from my local machine. On that NFS server there is a user with a group. But when I write a file from some local application to that storage, that file has a different user belonging to a different group. How can I force my local application to pretend to be the user from the NFS machine?

This also causes trouble when I want to modify existing files - I don't have write permissions...

You have to force on the server side. On the exports file you have to specify anonuid=xxxx,anongid=xxxx on the option of the directory exports. Replace xxxx with server userid (anonuid) and server groupid (anongid)
