      How to share folders with OwnCloud read-only users

      Requirements
      Onwcloud Plugin activated in Plugins section

      Description
      This guide is gonna show you how to share your folders that are stored in your NAS storage with OwnCloud users.

      Installation
      First thing to know is that OwnCloud users are imported from your OMV configuration.

      That means that they use your web user (www-data) to access all folders, and by the way, with admin privileges, so be very CAREFUL because if something is deleted in OwnCloud, it is really deleted in your storage !!!
      So here is what you have to do :
      1. Create on your OMV administration panel a usertest within the users group :

      2. Create a ReadOnly group where you can add your usertest :

      3. Go to your Shared Folders, choose the folder you want to share and
        click on Privileges, there you can tick the Read-Only box for your
        ReadOnly group :
        [IMG:http://s4.postimg.org/f59ug2azx/image.png]
      4. Go to your OwncLoud plugin administration and in the Shares tab you can add the folder you want to share :

      5. Go to your OwnCloud page and add the External Storage Support :

      6. Then go to the Users page :
        [IMG:http://s23.postimg.org/satn8n0jf/image.png]
      7. Here you can see all the users imported from your OMV configuration
        (you can see that the user usertest goes with the ReadOnly group) :
        [IMG:http://s24.postimg.org/b1zonbuok/image.jpg][IMG:http://s24.postimg.org/9a6psfbbn/image.png]
      8. After that verification go to the Admin page :
        [IMG:http://s30.postimg.org/gq8nb3tch/image.png]
      9. Here you can see all the folders that you added previously in the Shares Tab from the OwnCloud plugin (here's mine) :
        [IMG:http://s30.postimg.org/6l5ur62bz/image.png]
      10. You can add more by clicking on Add Storage and choose Local :

      11. There you have to fill in the field with the path of your folder on
        your storage, here is how you can find it (by connecting to your OMV
        with SSH) :

        Source Code

        For example you can add the path /media/517da1a9-99a8-48b7-94ec-e937566a740d/Films to add your Films folder.

      12. Then you have to make it applicable only to the admin group :
        [IMG:http://s11.postimg.org/iswdj6xld/image.png]
      13. You can also uncheck the following box (as you wish) :
        [IMG:http://s18.postimg.org/fr21wspbt/image.png]
      14. After that go to your Files, you can see that the admin group have the privilege to delete files :
        [IMG:http://s14.postimg.org/3n8iv8h9b/image.png]
      15. Log out from your admin account and log in with your usertest account :
        [IMG:http://s14.postimg.org/45hwzorxd/image.png]
      16. You can see that there is nothing here :
        [IMG:http://s14.postimg.org/vdsjc95y9/image.png]
      17. Return to your admin account, we now have to share the folder with the ReadOnly group :
        [IMG:http://s27.postimg.org/twje2p50j/image.png]
      18. Uncheck all the edition boxes :
        [IMG:http://s7.postimg.org/ra8m9v0a3/image.png]
      19. Now log in to your usertest account, you can see that there is not nothing anymore but there is still the Delete Option :
        [IMG:http://s28.postimg.org/rlcp1mb63/image.png]
      20. Try to delete the folder :
        [IMG:http://s22.postimg.org/81chym7s1/image.png]
        You can't !!!

        So you now have shared folders where your friends can't mess up with your files.

        Cheers mates.
