Hi Brian, I've tried to export a kernel mount via Samba with AD. I can read files but I cannot write files~~~~>< It shows the acl errors when writing files. As you said, it may need to store Windows ACLs in xattrs with the acl_xattr VFS module, which is currently available in Samba. I am not sure if this error is what you mean. If it is, the acl thing is available in Samba now, then why this error shows? This confuses me a lot.....>< Thanks~~~~^^ 2011/6/2 Brian Chrisman <brchrisman@xxxxxxxxx>: > On Wed, Jun 1, 2011 at 11:54 PM, Sylar Shen <kimulaaa@xxxxxxxxx> wrote: >> Hi Brian, >> Thanks for the information. >> Please allow me to confirm what you said. >> You're saying that general samba server worked well with Ceph. >> But It's not OK to integrate with Windows Active Directory right now >> because the acl_xattr VFS of Ceph is different from normal samba >> server. > > I simply haven't tested this yet.
