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.
