new smb remote fails

[gonzametal]

I have a clean install from sources in debian of Xen Orchestra. The product is not running as root.
When I create a new smb remote to a Windows Share (with remote username and password) It fails with the following error

{
"errno": -13,
"code": "EACCES",
"syscall": "mkdir",
"path": "/run/xo-server"
}

What can I do? Thanks
