NWBC and SSO: Logon with/without SNC (Secure Network Communication)

[sandra_thimme]

If SNC is activated in SAP GUI and in NWBC, the logon popup never appears again.

This is exactly what you would expect from a

Single Sign-On technology, but sometimes you might still want to have a logon popup (for testing purposes for example).

If you have previously used the SAP Logon Pad, you might know the options SNC Logon with Single Sign-On (Enter) and SNC Logon without Single
Sign-On (Shift+Enter).

Unfortunately we do not have this kind of "switch" in NWBC.

Fortunately however there is a workaround:

You can use the existing external service (delivered with 7.40) /nwbc-no-sso.

This alias calls the NWBC service without support of certificates and always forces a logon screen.

Alternatively, you can create your own external alias in transaction SICF.
