I have a .NET Excel Plugin created with Add-in Express 8.2.
This Excel Add-in performs REST calls to a backend which retrieves data and inserts it into a spreadsheet.
Currently this Excel Plugin authenticates using basic authentication (we set the authentication header).
We prompt the user for a username + password before performing the REST call.
What I would like to do is perform the authentication using SAML.
Unfortunately SAML is a web authentication protocol, so performing a SAML negotiation within the plugin is not trivial.
My plan/idea is to use a WebBrowserControl within the Excel Add-in ribbon which performs the SAML authentication.
Would it be possible to use a WebBrowserControl in the Excel Add-in this way? |

Hello Henjo,
Consider placing such a WebBrowser control on a custom pane. You can't show a custom control on the Office Ribbon; this is by design.

Ah thanks!
I don't have a custom pane in my current plugin.
Would it be possible to add a custom pane with the WebBrowserControl on it, but only use it programatically?
So, I would use it to access the REST endpoint (and let the WebBrowserControl handle SAML authentication) without letting the User see the control and pane?
Do you have a clear example of adding such a (preferably hidden) pane + a custom control on it? |

Henjo,
Check section Step #12 ?Â?Ð?ã Creating Advanced Task Panes in Excel 2000-2019, see the PDF file in the folder {Add-in Express}\Docs on your development PC.
To prevent a task pane from being shown, set ADXExcelTaskPane.Visible = false in the ADXExcelTaskPane.ADXBeforeTaskPaneShow event.
