You need to use the username and password that you also use when logging on to the network with your workstation. The username usually uses the format: firstname.lastname@example.org
Depending on the wishes of your organization you will need to enter a domain name or it might be preselected for you. If the domainname is empty by default, please enter the domain name 'SSP'.
Check the information you entered. You probably made a mistake entering your username and/or password. Please enter those again.
