Hi,
I am trying to set a sharepoint 2019 claims-based web app as being available to anonymous users since this web front should be reachable from the internet.
The problem is that the web browser still prompts me for credentials.
I have followed this guide to set it up:
https://www.enjoysharepoint.com/enable-anonymous-access-sharepoint-2013/
And I have followed these guides to troubleshoot:
https://www.koskila.net/troubleshooting-anonymous-access-sharepoint-onpremises/
https://www.sharepointdiary.com/2015/05/fix-login-prompt-on-anonymous-access-enabled-sharepoint-sites.html
It seems that I have done everything as one should.
The problem is that I get a credential prompt, and when I click "cancel" I still get to see everything on the site.
If I use fiddler and click "cancel" I can see that I get a HTTP 401 from a custom style sheet in the Style Library. But that library has anonymous access enabled on it. The entire style library inherits permissions from the site which also has anonymous access enabled on the entire site.
By the way, the site collection feature "Limited-access user permission lockdown mode" is not activated.
Any thoughts on what the next step for troubleshooting might be?
are all files in Pages and Style library published with major version? Also check is master page (Catalogs > Master pages) published with major version.
There we have it!
The custom.css that the master page used was only in version 0.1. After publishing it to 1.0 it worked!
I can reproduce the issue in my SharePoint.
To resolve this issue, when you set Anonymous Access, uncheck the box for “Require Use Remote Interfaces permissions”.

Unfortunately, this didn't resolve it for me. I tried disabling it on the problem site and at the web application but I still get the prompt.
Type the Regedit in the Run menu -> Locate the Registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa -> Check whether an entry by the name DisableLoopbackCheck is present in the folder. If it is not present, right click Lsa -> New -> Click DWORD -> Specify the value for the entry as DisableLoopbackCheck -> Double click and open the entry, specify the value as 1.
It wasn't there, I added it but it didn't change anything. Still getting prompt.
Whether you restart IIS?
Sorry, forgot to mention. I restarted the server after the change in regedit. Still getting prompt
