NFSv3: try get_root user-supplied security_flavor
Thanks to Ed Keizer for bug and root cause. He says: "... we could only mount the top-level Solaris share. We could not mount deeper into the tree. Investigation showed that Solaris allows UNIX authenticated FSINFO only on the top level of the share. This is a problem because we share/export our home directories one level higher than we mount them. I.e. we share the partition and not the individual home directories. This prevented access to home directories." We still may need to try auth_sys for the case where the client doesn't have appropriate credentials. Signed-off-by: J.
