[Samba] Samba 4.6.5 and quota

[Stephan]

Hello everyone,

I'm having a hard time getting samba 4.6.5 to return the quota to 
Windows clients. samba has been compiled with quota-support:

/usr/local/samba/sbin/smbd -b | grep 'QUOTA'
    HAVE_SYS_QUOTAS
    HAVE_SYS_QUOTA_H
    HAVE_RPCSVC_RQUOTA_H
    HAVE_GETQUOTA_RSLT_GETQUOTA_RSLT_U
    HAVE_NFS_QUOTAS
    HAVE_QUOTACTL_LINUX
    WITH_QUOTAS

However the client shows the size of the underlying filesystem, not the 
free space according to quota. The filesystem is ext4.

I have a script which worked under samba 3.6 and 4.2 as "get quota 
command" but can't work under 4.6.5 because this one only asks for a 
strange combination of type and uid/gidnumber: It combines the 
user/group quota type (1 and 3) with uid/gidnumbers of -1 which is not 
helpful since there is obviously no way to figure out the quota for user 
X without knowing who user X is... Is this a bug or a feature that I 
just don't understand ?

get_quota: Running command /usr/local/bin/getsambaquota.pl . 1 -1
get_quota: Running command /usr/local/bin/getsambaquota.pl . 3 -1

Regards,
Stephan
