Error 255 returned when creating Samba usershare in Nautilus

This document (7018701) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11 Service Pack 4 (SLES 11 SP4)

Situation

Upon right-clicking a folder in Gnome's Nautilus file manager, choosing "Sharing Options," selecting the "Share this folder" box and clicking the "Create Share" button in the open dialog, the following error is returned:
'net usershare' returned error 255:  net usershare add: cannot convert name "Everyone" to a SID. Access denied.



Resolution

Since samba-client version 3.6.3-76.1, a new global option is required in smb.conf.
hostname:~ # vi /etc/samba/smb.conf
Add this option under the [global] section:
client ipc signing = auto
After the change is written, restart the samba service:
hostname:~ # rcsmb restart

Cause

Several CVEs were addressed for this samba-client package with the update to version 3.6.3-76.1.  As a result of these changes, this new client ipc signing configuration option is required when creating usershares through Nautilus.
