You can now mount SMB/CIFS on ChromeOS

Specifically, SMB/CIFS, not just shares from Samba (a specific implementation of an SMB/CIFS server).

Yes, you are correct, title changed to reflect this.

Important note, this is not a feature provided by Google; it is "offered by www.eisbahn.jp/yoichiro" per Chrome Web store.

Has anyone gotten it to work? I've tried connecting to shares on Windows 7 and Windows Server 2008 without luck.

It appears that some it is rather particular with the dialect of SMB at the time: https://github.com/yoichiro/chromeos-filesystem-cifs/issues

It's been a while since I messed around with SMB/CIFS on Windows servers, but IIRC you can force the server to downgrade the version of CIFS it will support. I remember having to adjust a server that needed to support older clients. Based on the comments from the post, it sounds like this is the problem.

A quick Googling turned up these:

why not follow the smbnetfs or fusesmb and create a whole tree for all the shared discs on the network?
