Hello,

I recently mounted an NFS export to a RedHat 7.4 system from our NAS (FS7610) via NFS 4.1.  I setup idmapd.conf, and I see users instead of "nobody" when I list the files in the directory.  Things get strange, however, when I try cd into a directory that does not have the execute bit set for "other".  I get a permission denied message.  The user I'm using is the owner of the directory, and belongs to the group that owns the directory, so I shouldn't be denied.  I went as far as to export the directory with no_root_squash, and root gets permission denied errors under the same circumstances.

If I mount the directory with NFSv3, everything works as expected.  Most of the troubleshooting steps I see online involved modifying the NFS Server, but I don't think we can reasonably do that given this is the Equallogic NAS FS7610.  I have verified that our NAS is set to handle up to ver 4.1.

Does anyone have suggestions on what might be going on here, or how I can trouble shoot this better?  Without server side tools, I'm at a loss.
