Hi all,


Upgraded to Lion from a retail build of Snow-Leopard, upgrade went fine, but noticed i can connect SMB fine to my Win7 shares, but when doing a "mount" command on the MBP side, all mounted shares are read-only !


Permissions for this user are correct (it worked great in Snow-Leopard) with no changes to the Windows side.


Also i am giving credentials when i mount the share.


I realize Apple have written their own SMB stack since they cant distribute Samba anymore, but surely it can mount shares read-write, or is the implementation not ready for prime-time and mounts read-only for now until Apple correct the issue?




MacBook Pro, Mac OS X (10.7)

    It is definitely a problem.

    In my case a Win XP system.

    Lion -> Win XP no problem

    Win Xp -> Lion mount Read/Only


    Boot Lion machine with 10.6.8 - no Problem mounts R/W.


    Some have reportedproblems involving home directories, but in this case it a separate volume not the Lion or 10.6.8 volume.


    I have reported it to Apple.

    Hi Steve,


    When you say Lion -> Win XP, do your shares mount read-only or read-write?


    I'm not trying to mount from Win 7 (or XP) -> Lion, more the other way around.


    I'm interested to know if others have it working in that direction (and mount as read/write)?

    I am experiencing somewhat of the same issue.


    When I try to open an excel document located on my lion server from a windows machine I get an error saying "File cannot be accessed. The file may be read-only, or you may ben trying to access a read-only location". I can however create folders and copy over documents no problem. This makes absolutely no sense to me.

    You described my situation as well.


    I have a Windows XP computer -> Lion SMB share that mounts correctly but has "challenges"

    - Files and folders can be created but error messages are displayed on the Windows side. Refresh the window and they are there.

    - Files and folders can't be renamed or deleted


    A Snow Leopard Mac on the same network -> Lion SMB share works great


    Prior to upgrading to Lion the same shares on Snow Leopard worked flawlessly.

    I'm having the same issue with office documents on Lion 10.7 shares.  Files appear to be read only, folders appear to have read/write access.  Anyone got a solution?

    I was experiencing the same issue when using office 2003. What worked for me was to upgrade to office 2010. Not much of a cheap solution, but it did solve the problem.
