NAV 2015 Web server installation and config

Hello Guys

I have installed dynamics Nav 2015 and i needed users to access Nav via web client, but after successful installation when ever i tried it using any active directory used it shows that the logged user is an administrator account.I never configured the web client before.Note:The IIS server is installed as default

and if you have IIS and web Nav server step by step installation and config would be helpful
