Hello everyone,

I'm experiencing a strange problem with Samba Version 4.1.4-SerNet-RedHat-7.el6

I have setup a share where users can put stuff (permissions are set to 777 just to be sure for now), but sometimes when I try to copy entire directories an error pops up:

Unable to copy some_file_name.ext: Request not supported (0x80070032)

This usually happens mostly when directories contains a Thumbs.db files and Windows XP suffers more about this since it stops on error.

Windows 7 seems to be ok, since errors can be ignored. Not tried with 8.

What is the cause?? I have no idea...

here follows my smb.conf

workgroup = WORKGROUP
realm = MY.REALM
netbios name = SERVER
server role = active directory domain controller
allow dns updates = nonsecure and secure
dns forwarder =
nsupdate command = samba_dnsupdate
server services = rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbind, ntp_signd, kcc, dnsupdate, smb
dcerpc endpoint servers = epmapper, wkssvc, rpcecho, samr, netlogon, lsarpc, spoolss, drsuapi, dssetup, unixinfo, browser, eventlog6, backupkey, winreg, srvsvc, dnsserver
dsdb:schema update allowed = yes
idmap_ldb:use rfc2307 = yes
create mask = 0777
force create mode = 0777
directory mask = 0777
path = /var/lib/samba/sysvol/cfm.local/scripts
read only = No
path = /var/lib/samba/sysvol
read only = No
path = /tmp/myshare
read only = No
