I cannot access a directory and I don't understand why:



The user 'exchange' is in the right group and can access on non mounted dir application1_exchange_test but not application1_exchange. The only difference is that application1_exchange is a nfs mount.

  • The issue will most probably be to do with the nfs root_squash option that is implemented by default. I would suggest that you take a look at the man pages for "exports"

  • Can you unmount that filesystem and check the output of ls -dl application1_exchange ? On some operating systems, the permissions on the underlying mount point matter.
