Getting Login Prompt on Anonymous Access Enabled SharePoint Sites?
Problem: We Enabled anonymous access to SharePoint 2013, But still, users are getting Login prompts!
Here is the checklist for troubleshooting:
- Anonymous access must be turned on both at the Web Application level and at the SharePoint site level. Double-check your settings with How to Enable Anonymous Access in SharePoint 2013
- On publishing sites, try disabling the feature “Limited-access user permission lockdown mode” at the site collection level.
- If the default home page, say default.aspx page is not published & approved, users get a login prompt!
- If any referenced resources like images, scripts, CSS files, etc from other libraries require authentication – You’ll get an authentication prompt! E.g. You may have a CSS style sheet from a library, which may not allow anonymous access! Check the permission for the specific library and grant anonymous users to “read” the content.
- Navigate to the IIS Virtual directory on the File system using Windows Explorer, Go to the Security tab, make sure that “Everyone” has Read privileges. If not, add it!
- In IIS, expand your web application, click on “Authentications”, make sure “Anonymous Authentication” is enabled.
- In SharePoint 2013 Central Administration >> Application Management >> Manage Web applications, select the web application and click on “Anonymous Policy”. Make sure that “None – No Policy” is selected.
- If you enabled Anonymous access at list/library level: Delete unique permissions once, stop inheriting permissions and then grant anonymous access again.
