Synology NFSv4 with id mapping
Disclaimer: ID mapping without a Kerberos server only works halfway with NFSv4, it seems. I
managed to get the correct usernames to show up on my client when listing files, but creating new
files always creates them as user nobody because the Synology doesn't map anything in that case.
[This bug report][1] and the [linked thread][2] suggest this is normal behaviour of idmapd
when
not using Kerberos for some reason. (EDIT: [More detailed explanation.][3])
