What type of accounts does the -x parameter target when using smbpasswd?

The -x parameter in the context of the smbpasswd command specifically targets user accounts that have been enrolled in Samba. When using this command with the -x option, you are attempting to delete a Samba user account, which is mapped to a local or domain user in your environment. This is commonly used for managing user permissions and access to Samba shares.

Since the focus of smbpasswd is on user accounts involved in the Samba service, it's essential to ensure that any user you want to manage is already part of the Samba system. The deletion of an account using -x will remove that Samba user from the Samba password database, impacting their ability to access shared resources managed by Samba. This context clarifies that the command is not directly concerned with guest, service, or administrator accounts in the same way it is with standard user accounts.
