Synology NAS beginners guide | Part 12 | Groups and Permissions


In this video we take a look at how you create and edit Groups and Permissions, as we prepare to make our network shares accessible on our Synology NAS. We work with group permissions rather than individually assigning permissions, because Groups are seen as a more efficient way of working. So if on our Synology NAS we use groups to setup our permissions, not only do we reduce the chance that we assign the wrong permissions to a user. We can also implement permission changes more quickly.

Note: For a home network with only one or two users, there is nothing stopping you from by passing Groups and just manually assigning folder permissions individually to each of your users accounts. In this instance rather than setting permissions in Groups, you simply set user permissions by editing a User account.

  • Log into your NAS using your Administrators credentials 
  • From the desktop of DSM select Control Panel
  • Now under the heading File Sharing select User and Group
  • In the User and Group panel select the Group tab button so that you can either edit or create a Group.  

Note: By default you will find three groups, Administrators, http and Users. While there should be no need to change any permissions in Administrators and http. As all new user accounts will automatically get added to Users. We like to edit the Users group to give all users access permissions to specific network shares.

  • In order to create a new Group if you select Create you will open a Group Creation Wizard
  • In the group name field enter the name of your group

Note: When naming groups it’s important to follow set conventions. So while a group name is not case sensitive and can be between 1 and 32 characters in length. You can not have a space as the first and last character or use any of the following symbols:

  ! " $ % & ' ( ) * + , / : ; < = > ? @ [ ] \ ^ ` { } | ~
  • The Group description does not need to be filled. However it can be useful to make a note of what a new groups is for.

Note: The Description field is case sensitive and limited to 64 characters

  • After choosing Next you can assign user accounts to your new Group.
  • When you select Next you will be shown the network shares on your NAS. Tick the check boxes to any shares that you want your group to have permissions to.
  • Now at Assign Group Quotas, we can limit the amount of data this Group will be able to save to your NAS. This option can be useful if you have limited storage capacity on your NAS.
  • Set Group Speed limits will stop members of this group from being able to use too much internet bandwidth when using certain services.
  • At the Summary after clicking Done, our new group is created.
