We have an Internet Facing SP 2013 web application for which Anonymous Authentication is enabled. Funny thing we are encountering is that on trying to access this site from Mobile, we are getting Username Password prompt, however on clicking Cancel the site opens up with all the contents. I have gone through all the various forums and tried the following steps :
- Edited the compat.browser file and changed capability name="isMobileDevice" to false
- Tried making changes in the web.config file of the web app file and tried adding the following browserCaps tag and adding Filter for isMobileDevice=false
- The MobileBrowserView feature is deactivated on activating it I'm getting a 401 Unauthorized error. So deactivated the feature again.
Also I'm not able to recreate this issue on my desktop If I add ?Mobile=1 to my url. On doing this I'm not getting a credential prompt. So I'm not able to trace the issue in Fiddler as well as a result of this. Also this same set-up is running fine on a lower environment and I'm not getting the credential prompt, however this issue is occuring in the PROD environment.
Please suggest if anyone has encountered this before and the fix for this.
