Basic Authentication Warning
In addition to the "anonymous logon" user name and password fields, the Security Accounts property sheet contains the following authentication options:
Allow Anonymous Connections
When this check box is selected, FTP logons in which the user enters a user name of "anonymous" will be processed. These anonymous connections will be processed on behalf of the Windows NT user account specified on the Security Accounts property sheet. When this check box is cleared, users will be required to enter valid Windows NT user names and passwords to log onto the FTP service.
Allow only anonymous connections
When this check box is selected, all user logons except "anonymous" will be rejected.
Warning
FTP user names and passwords are sent across the network in clear text. When this check box is cleared, Windows NT passwords will be sent to the server without encryption. This check box is checked by default for security reasons.
