We have developed angular application (UI in angular 6 and Web API (.Net framework 4.6.1)) with window authentication using LDAP. To enable the window authentication credential prompt, we have added authentication= window in Web API Config and also enable same in IIS. It is working fine in all the browsers, but not working in IE11. We have to support two domain users, without a credential prompts I will not be able to manage it.
Is this the right way to implement it? If I impalement SAML, will it work for me for the given requirement.

What I have tried:

I have referred all the below link and applied, IE settings to enable it but still not working.

There is no prompt for a username and password in IE because "Windows Authentication" uses the account of the user that launched the browser. The only time you get a prompt for credentials is in other browsers that don't have support for NTLM authentication turned on by default or not it's not supported.
