Logon Using Basic Authentication. 

Use

If you use Basic Authentication to log on to the ABAP Application Server, you can choose either a standard SAP user or an Internet user:

●  The default SAP user is the user name entered in transaction SU01.

●  The Internet user is the alias name. This can be longer than the normal SAP user name. This can also be set in SU01.

Depending on the settings, the input in the HTTP popup for Basic Authentication is interpreted as either a user name or an alias.

Activities

If you want to change the user type for the Basic Authentication logon procedure in a service or service node, proceed as follows:

  1.  In transaction SICF, double-click the required service or service node.

  2.  Choose  Change

  3.   

  4.  Under Logon Data/Authentication, choose Standard SAP User or Internet User. 

If you make this setting in a service node, the data is passed on to all services under this node.

  5.  Save your entries by choosing  Save.
