Logging On to SAP Web Application
Server 
You can choose from several different logon procedures when you use a HTTP request to log on to SAP Web AS. You can configure the procedure individually for each service or for an entire service node, including all its services.
At least one HTTP request handler must have been entered for the service or service node.
· For each ICF service, you can specify which logon procedure must be used to execute it. You have the following options:
¡ Standard (default): When you log on, multiple checks are run in a specified order.
¡ Alternative Logon Order: When you select this option, you can choose the checks yourself, and the order in which they run.
¡ Logon Data Required: Only the logon data specified in the service (User, Password, Client, and Language) is used to check the logon.
¡ Client Certificate (SSL) Required: Logons are performed using X509 Client Certificate only.

You can use only one of these options for each service or service node.
· If you use the standard or alternative logon procedures, you can use the All Logons checkbox to specify whether the appropriate checks are run (in the specified order) until one of the logon procedures is successful (checkbox activated), or whether the logon is rejected with a message as soon as a logon procedure fails (checkbox not activated).
· For each service, you can define an individual response page that appears if the logon fails.

· Logon with Client Certificate
· Settings for Basic Authentication
· Determining the Logon Language
