I think I solved it.

If Samba is compiled with support for quota, but we don't intend to 
use that feature, we may simply set this global option:

get quota command = /bin/echo 0 0 0 0 0 0 0 1024

A more sophisticated solution is to create /usr/local/sbin/query_quota 
or something similar, and let it adhere to the specification found in 
smb.conf(5):

This parameter should specify the path to a script that queries the quota information for the specified user/group for the partition that the specified directory is on.

Such a script is being given 3 arguments:

directory

type of query

uid of user or gid of group

The directory is actually mostly just "." - It needs to be treated relatively to the current working directory that the script can also query.

The type of query can be one of:

1 - user quotas

2 - user default quotas (uid = -1)

3 - group quotas

4 - group default quotas (gid = -1)

This script should print one line as output with spaces between the columns. The printed columns should be:

1 - quota flags (0 = no quotas, 1 = quotas enabled, 2 = quotas enabled and enforced)

2 - number of currently used blocks

3 - the softlimit number of blocks

4 - the hardlimit number of blocks

5 - currently used number of inodes

6 - the softlimit number of inodes

7 - the hardlimit number of inodes

8 (optional) - the number of bytes in a block(default is 1024)
