Notes: 
•  Users that are automatically registered belong to the "hdusers" group. They can be added to other groups 
from within groups settings. Added users will be listed in "Users" - "External Users". To delete a user that was 
registered automatically, select that user and click Delete External User.
•  If both read-only and read & write permissions are given to a user, the user will have read-only access. The 
most restrictive attribute will apply.
•  Use OS X 10.5 or later with external authentication. Earlier versions of OS X aren't supported.
•  To access access-limited shared folders from OS X 10.7, use AFP instead of SMB, under “LAN Protocol Support”, 
check "AFP (Mac)" on the destination folders to use AFP.
•  If access restrictions are set for users and groups from the authentication server, guest and anonymous 
connections will not be possible with AFP connections.
•  FTP connections do not support authentication with an external SMB server.
•  If using a Windows PC for external authentication, the default Windows SMB security settings may need to 
be changed. An easy way to do this is to run the File Sharing Security Level Change Tool, available from this 
product’s download page on www.buffalotech.com. This utility will let you easily change or restore your 
Windows security settings to work with external authentication.
Converting Local Users into External Users
If using an external SMB server for authentication, you may convert any local users into external users. This way, the 
LinkStation will have a user list that matches the users in the external SMB server, and access restrictions for this 
LinkStation’s shared folders may be assigned to the converted “external” users.
Follow the steps below to convert a local user into an external user. If a local user is converted, their user information 
(including passwords) will be removed from the LinkStation. External users cannot be reverted to local users.
Note: External authentication should be enabled before local users can be converted. For more information on 
external authentication, refer to the “User Authentication with an External SMB Server” section.
In Advanced Settings, click File Sharing.
Click 
 to the right of "Users".
In the user list screen, check any users to be converted to an external user, then click Convert to External User.
Click OK.
Enter the confirmation number and click OK.
Converted users are displayed under the "External Users" tab. You can then configure access restrictions for external 
users.
