Experience Builder login issue with Enterprise portal data (version 11.3)

[andreoudi]

Hi everyone,

I’m encountering an issue that seems similar to a post from 2021 (Experience Builder Not Supporting Enterprise Porta... - Esri Community), and I’m wondering if anyone else has run into this recently.

I have a web map hosted on ArcGIS Online that includes data from our Enterprise portal (version 11.3). This map has been used successfully in a Web AppBuilder application for some time.

Now that Web AppBuilder is scheduled to be retired in Q1 2026, I’m rebuilding the application in Experience Builder. However, when I add the map to Experience Builder, I’m prompted with a login window asking for a username and password. Our organization uses SAML authentication, and I’m unable to proceed beyond this step.

I also tried adding the data directly via URL in Experience Builder, but that resulted in a client_id error.

The Web AppBuilder app also prompts for login, but I only need to click "OK" to access the data.

We’ve previously built Experience Builder apps using data from our Enterprise portal without any issues, so this setup has worked before.

Could this be a bug introduced in a recent Experience Builder update?
Any insights or workarounds would be greatly appreciated!

Thanks in advance,
Maria

Hi @andreoudi,

We've received the same feedback, but can't reproduce the issue. Could you provide a test environment to help us troubleshoot?  Thanks.

Thanks,

Hi @Ke_Xu,

Thank you for looking into this. I just want to clarify that the issue only appears for feature layers that are not publicly shared.

Would it be sufficient if I send you the REST URL of a test layer? If so, could you please share your email address so I can forward it to you?

Thanks in advance,

Maria
