The fact that serverino gets disabled looks like a bug. As Steve said, the problem seems to be related to ACL. You should open a bug and provide dmesg and network capture as documented here: https://wiki.samba.org/index.php/Bug_Reporting#cifs.ko Cheers, -- Aurélien Aptel / SUSE Labs Samba Team GPG: 1839 CB5F 9F5B FB9B AA97 8C99 03C8 A49B 521B D5D3 SUSE Software Solutions Germany GmbH, Maxfeldstr. 5, 90409 Nürnberg, DE GF: Felix Imendörffer, Mary Higgins, Sri Rasiah HRB 247165 (AG München)
