[Samba] getting error with setfacl

[James D. Parra]

Hello,

I have joined the Linux server (Suse 11.2) to the Windows domain (win2003) and users can login to the server using their window's domain credentials. Also can view all of the domain groups using 'wbinfo -g', however when I try to set the acls on a local dir' I get the follow error;

#setfacl -m g:DOMAIN\\groupname:r /tmp/testacl
setfacl: Option -m: Invalid argument near character 3

The same error occurs if I use a domain user, although I can add a local Linux user or group. What am I overlooking?

Many thanks on advance.

James
