[Samba] chown: changing ownership of 'test': Invalid argument
Hi All, I have a very weird issue on one of my servers. I think I might just be missing something quite obviously...

Hai Ian,
Can you run my setup debugger..
https://raw.githubusercontent.com/thctlo/samba4/master/samba-collect-debug-info.sh
Anonimize where needed and post output.
Because when i run this, it works fine.
chown -v username test-own.txt
changed ownership of 'test-own.txt' from root to username
And yes, this user only exist in AD.
Check if attr and acl are installed also.
And if the smb.conf below is complete then your missing:
# For ACL support on member servers with shares
vfs objects = acl_xattr
map acl inherit = Yes
store dos attributes = Yes
The difference between you and me, in smb.conf as far i can tell now.
Me backend AD. You RID.
Me
kerberos method = secrets and keytab
dedicated keytab file = /etc/krb5.keytab
winbind refresh tickets = yes
You ( only secrets )
I've just tested these versions because today my vpn needed the upgrades of
samba also.
I've tested and upgraded from 4.8.9 upto 4.8.11, 4.9.6 and 4.10.2
It still might be a bug, but i need more info.
Greetz,
Louis

There are numerous lines I would add, but they do not really have anything to do with your problem. A last thought, do you have any users in AD that also occur in /etc/passwd ? Rowland

that looks fine, execpt, smb.conf, your only using the server for
authentication, no shares?
then we can reduce the install a bit.

Hai Ian,
Can you run my setup debugger..

Anonimize where needed and post output.
Because when i run this, it works fine.
chown -v username test-own.txt
changed ownership of 'test-own.txt' from root to username
And yes, this user only exist in AD.
Check if attr and acl are installed also.
And if the smb.conf below is complete then your missing:
# For ACL support on member servers with shares
vfs objects = acl_xattr
map acl inherit = Yes
store dos attributes = Yes
The difference between you and me, in smb.conf as far i can tell now.
Me backend AD. You RID.
Me
kerberos method = secrets and keytab
dedicated keytab file = /etc/krb5.keytab
winbind refresh tickets = yes
You ( only secrets )
I've just tested these versions because today my vpn needed the upgrades of
samba also.
I've tested and upgraded from 4.8.9 upto 4.8.11, 4.9.6 and 4.10.2
It still might be a bug, but i need more info.
Greetz,
Louis

[Samba] chown: changing ownership of 'test': Invalid argument
I forgot, post also:
cat /etc/idmapd.conf
( im adding it in the debug-collector atm )
There might be a mis in detecting the Domain or Local-Realm.
I suggest, add this :
Domain = jeoffice.jacklin.co.za
Local-Realm = JEOFFICE.JACKLIN.CO.ZA
see if that helps.
Greetz,
Louis

Hai Ian,
Can you run my setup debugger..
https://raw.githubusercontent.com/thctlo/samba4/master/samba-collect-debug-info.sh
Anonimize where needed and post output.
Because when i run this, it works fine.
chown -v username test-own.txt
changed ownership of 'test-own.txt' from root to username
And yes, this user only exist in AD.
Check if attr and acl are installed also.
And if the smb.conf below is complete then your missing:
# For ACL support on member servers with shares
vfs objects = acl_xattr
map acl inherit = Yes
store dos attributes = Yes
The difference between you and me, in smb.conf as far i can tell now.
Me backend AD. You RID.
Me
kerberos method = secrets and keytab
dedicated keytab file = /etc/krb5.keytab
winbind refresh tickets = yes
You ( only secrets )
I've just tested these versions because today my vpn needed the upgrades of
samba also.
I've tested and upgraded from 4.8.9 upto 4.8.11, 4.9.6 and 4.10.2
It still might be a bug, but i need more info.
Greetz,
Louis
