After done with Inhouse Distribution Certificate (as Shown in above figure) and app id creation process using Enterprise Distribution Credentials of your app on Apple Member Center.

Constructing your website
Upload these items to an area of your website that your authenticated users can access:
- The app (.ipa) file
- The manifest (.plist) file
Your website design can be as simple as a single page that links to the manifest file. When a user taps a web link, the manifest file is downloaded, which triggers the downloading and installation of the apps it describes.
Here’s a sample link:
<a href="itms-services://?action=download-manifest&url=http://example.com/ manifest.plist">Install App</a>
NOTE: Please dont change highlighted yellow text in above url.
Don’t add a web link to the archived app (.ipa). It’s downloaded by the device when the manifest file is loaded. Although the protocol portion of the URL is itms-services, the iTunes Store isn’t involved in this process.

For Mac OS X Server, use Server Admin to add the following MIME types to the MIME Types settings:
For IIS, use IIS Manager to add the MIME type in the Properties page of the server:
