If you have chosen 'NTLM' in 'Authentication type', you can specify the remote username format here. If you leave this empty, the default DOMAIN\username format will be used. You can use the optional <b>%domain%</b> placeholder to specify where the domain name appears, and the mandatory <b>%username%</b> placeholder to specify where the username appears. <br /><br />Some widely used formats are <tt>%domain%\%username%</tt> (MS Windows default), <tt>%domain%/%username%</tt>, <tt>%domain%+%username%</tt> and just <tt>%username%</tt> (if there is no domain part).
