A NAS server may not know the groups a user belongs to. If _POSIX_CHOWN_RESTRICTED is enforced by the NAS server, and it doesn't have access to the group data, it won't allow the change if it's not aware of the group(s) the file owner belongs to.
Although I had thought the group data was part of the NFS protocol? That may have changed in NFSv4, as I can see how trusting a client to supply gids could potentially be a security issue. I know my the first thing I do when I have any problem at all with NFSv4 is try NFSv3. Especially in a heterogeneous environment where various OS breeds and flavors are sharing NFS mounts. (Yeah, I avoid NFSv4 whenever possible.)
Being shared R/W to everyone shouldn't matter.

MEMBERS(1) General Commands Manual MEMBERS(1)
NAME
members - outputs members of a group
SYNOPSIS
members groupname
DESCRIPTION
This manual page documents briefly the members commands. This manual page was written for the Debian GNU/Linux distribution.
members is a program that sends a space-separated list of secondary member names to its standard output.
OPTIONS
The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below.
-a, --all
Show all group members on one line. This is the default.
-p, --primary
Show only primary group members.
-s, --secondary
Show only secondary group members.
-t, --two-lines
Send two lines to standard output. First line is primary members, second line is secondary members. NOTE: This always displays two
lines, even if there are no members at all.
-h, --help
Show summary of options.
DIAGNOSTICS
Exit status is 0 (i.e. "success") if the group was found, and 1 (i.e., "failure") if the group was not found.
Technically, the exit status hinges on the output of getgrnam(3) as follows: if getgrnam(3) returns a null pointer, the exit status is 1,
and 0 otherwise.
BUGS
I don't know of any! If you find one, please let me know!
