Domain-level security Samba becomes a member of a Windows domain and uses the domain s primary domain controller PDC to perform authentication. Once authenticated the user is given a special token that allows him or her access to any share with appropriate access rights. With this token the PDC will not have to revalidate the user s password each time he or she attempts to access another share within the domain. Each of these security policies can be implemented with the global security option as shown in Table .

Samba Share-level Security With share-level security each share has one or more passwords associated with it. This differs from the other modes of security in that there are no restrictions as to whom can access a share as long as that individual knows the correct password. Shares often have multiple passwords. For example one password may grant read-only access while another may grant readwrite access and so on. Security is maintained as long as unauthorized users do not discover the password for a share to which they shouldn t have access. OS 2 and Window 95 98 both support share-level security on their resources. You can set up share-level security with Windows 95 98 by first enabling share-level security using the Access Control tab of the Network Control Panel dialog. Then select the Share-level Access Control radio button which deselects the user-level access control radio button as shown in Figure and press the OK button.
