On my Macbook (OSX Lion 10.7) I have samba sharing on : System Settings -> File Sharing ON -> Windows sharing ON my home folder shared only as my userid. When I connect my Android (Samsung Galaxy S2 with 2.3.3), NO Android app (AndSMB, ES File Manager, Astro, etc. ) connects with my Mac unless I share the folder anonymously (which is not desired). When I connect any Android app over SMB with a Ubuntu Linux SMB server it connects flawlessly. And from the other way, when I connect a Ubuntu Linux or Windows PC with my Mac it connects flawlessly. Is this a known Android or Lion issue ?
