Click OK.
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 connection.
• 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.
