Basemap Gallery not accessible after changing anonymous access setting in ArcGIS for Portal

Question

I updated the "Allow anonymous access to your portal" security setting from enabled to disabled.

After I did this, maps in our basemap gallery hosted on ArcGIS for Portal were inaccessible. When I changed the anonymous setting back to be disabled, the basemaps were accessible. All the maps within this gallery are set to be shared with everyone in Portal. My question is, if an item in ArcGIS Portal sharing settings is set to be viewable by anyone, why would needing anonymous access be enabled to view these specific items? I don't think it is a good security practice to allow anonymous access to the Portal, and it seems to share specific items with everybody should bypass that if anybody should be able to access them.

Hello @ArchitSrivastava .

I hope you are doing well also and thank you for the detailed response. Apologies for the delay, I was out of the office last week.

- I have ensured that the group is viewable by Everyone (public).

- One basemap was shared with everyone, but not the basemap group. I update the settings to be shared with the basemap gallery group as well. I toggled the allow anonymous access to be disabled temporarily, and the issue persisted.

* What is the version of ArcGIS Enterprise you are working with? (Will help me test this on my end)* 11.2

* Is there any error in Portal for ArcGIS Logs?* Nothing in the log files is relevant to the basemaps temporarily disabling anonymous access.

* Is there any error you can see in Developer tools of the browser?* Nothing relevant after temporarily disabling anonymous access.

After viewing the diagram in the reply, in theory, the basemaps should be visible while having anonymous access disabled, but still a hiccup somewhere in the process.

Hello @Brian_McLeer ,

Hope you are keeping safe and well.

As per my understanding of things. The "Anonymous Access" should not have any impact on the Basemap Gallery unless one of the items in the Basemap group is not shred properly.

I think you may have already checked these but let's just cover our bases before reaching out to ESRI Support:

* Ensure that the group (which is set in Basemap Gallery) is viewable by Everyone (Public) or by All organization members.
* Ensure that each basemap which you want to see in the "Basemap Gallery" is shared with "Everyone" and the "Basemap Group" (may have to check each item)

It seems to me that one or more item in the "Basemap group" may not be available to the user/users who are trying to access it.

Probably best explained by diagram below (based on what I have worked and understood from testing)

It would also be great if you can check/confirm the following as well:

* What is the version of ArcGIS Enterprise you are working with? (Will help me test this on my end)
* Is there any error in Portal for ArcGIS Logs?
* Is there any error you can see in Developer tools of the browser?

Hope it helps!

Thank you @DavidColey. I will continue to dig but sounds like it will be a support ticket. I appreciate your feedback.
