Some more news,

I tried mounting the same export from a macosx client and it succeeded.
There was a difference though when looking at the rpc.svcgssd output

rpc.svcgssd -vvf:

As you can see it uses a different sname and there are two requests, while I only see one with the linux client. Of course uid and gid are different too.

Kind regards,
