          It is also possible to authenticate users using a combination of either 
windows accounts or 
Sysax user accounts. If this option is selected and a 
username exists in both windows and Sysax user accounts, the server can be configured to use either Windows accounts or Sysax user accounts first to perform the authentication. The server may also be configured to 
login using the windows account and then use the sysax user settings.
