Processing the Logon

Use

When a user logs on to SAP NetWeaver Application Server (AS) ABAP when using SNC protection, the logon process is as follows:

  1. SAP GUI and the AS ABAP determines if the following are true:

    • Both parties have enabled SNC.

    • SAP GUI has not set the password logon flag.

    • There is a mapping to the SNC name provided by the security product to a user in the AS ABAP.

    • If any one of the above are not true, SAP GUI displays a logon screen, as long as logon with user ID and password are allowed by the profile parameter snc/accept_insecure_gui. Otherwise logon fails.

      As long as SAP GUI and AS ABAP are capable of using SNC, the logon is protected by SNC.

    • If all of the above are true, the process continues.

  2. SAP GUI displays an initial screen where the user chooses client from the list of available mappings.

    The user can also opt to choose a logon language.
