Alternative Logon Order
When you choose the alternative logon order, you can select the logon procedures of your choice, and change the order in which they are checked.
When you use the alternative logon order, you can include or remove the following procedures:
● Logon using HTTP fields
● Logon using SAP Logon Ticket (SSO)
● HTTP Basic Authentication
● Logon using SAP user and password (RFC logon)
● Logon with SSL certificates
● Logon using SAML
● Logon using user data stored in the service
You can change the order of the checks to meet your requirements.

If the All Logons flag is set, all logon procedures are checked one by one until a check is successful. If the flag is not set, only the first procedure in the sequence is checked. If it is not successful, an appropriate error appears.

A logon procedure is only checked when the corresponding logon data is also provided by the HTTP request.
To define an alternative logon order, proceed as follows:
1. In transaction SICF, call the required service or service node.

If you define the logon order in a service node, the settings are passed on to all services under this node, unless different data has been entered for them.
