Transaction webgui gives logon prompt. Transaction nwbc and soamanager do not.

[former_member197700]

How come if I run /nnwbc or /nsoamanager, Internet Explorer launches and takes me straight into those transactions, but if I run /nwebgui, I am prompted for a user name and password?  I want webgui to launch from the sapgui without a logon prompt.    Thanks in advance for any ideas!

Hello Clifton,

This is more a security-related issue, a SSO issue.

You can read SAP note 1257108, section "1.6. Special cases", first paragraph.

The WEBGUI can work without asking for credentials, as long as a SSO configuration be in place. In my test systems I configured SSO based on X.509 client certificates. Thus, calling the WEBGUI using HTTPS will always automatically logon the user, taking for granted that the user ID has a client certificate mapped in the system.

Kind regards,

Cris

Hi Cris,

Thanks for the info.  A couple of clarification questions:

1) So webgui is NOT a bsp application, correct?

2) For X.509 certificates to work with webgui, is it enough to have the user install the SSL certificate of the SAP server into their own browser?  (I tried and still got a logon prompt.) ... or does the SAP server need to also have a certificate for the user?

Hello Clifton,

Yes, WEBGUI is not a BSP application. It is another SAP web technology (also different from WebDynpro ABAP).

For the X.509 client certificates to work, you can follow this blog I wrote.

Kind regards,

Cris
