Figure 70. Configuring Proxy-Server
Specify whether the proxy server uses authentication.
Authentication
is
a procedure to verify user account information for the purposes of
access control.
If authentication is required to connect to the proxy server, check
Use authentication
and enter user name and password in the appro-
priate fields.
This will result in an attempt to perform an NTLM-
authorization followed by a BASIC authorization.
If the check box is unchecked, NTLM authorization will be attempted us-
ing the login under which the task (such as an update, cf. Section 6.6 on
pg. 60) is running.
If the proxy server required authorization, and user name and password
are not specified or rejected by the proxy for whatever reason, a dialog
requesting user name and password will be displayed. If authorization is
successful, the specified user name and password will be remembered
for subsequent use. Otherwise, authorization information will be re-
quested again.
Pressing the
Cancel
button in the authentication prompt dialog replaces
the current source of updates with the next one from the list; the authen-
tication parameters specified in that window or defined in the program
interface will be ignored. Therefore, the application will attempt NTLM
authentication based on the account used to launch the task.
If an ftp server is used to update, a passive connection to the server is estab-
lished by default. If this connection attempt returns an error, an attempt is made
to establish an active connection.
