Adding Authentication

InfoPath does not automatically configure server-only authentication options for you. However, when creating a UDC file, InfoPath automatically creates an authentication block within the UDC file that is preconfigured to use Office Single Sign-on. In order to use this authentication option, you'll need to uncomment the authentication block within the file and add both the SSO application ID and the CredentialType. Most of the time, you'll want to use the SSO credential to log onto Windows, for which you'll need to specify "NTLM" as the CredentialType. The full list of possible credential types is as follows:

The answer is here:
 Go to SharePoint Central administration --> Application Management -->  Authentication Providers. Then select the default zone. Make sure the right  Web Application is selected on the top of the page. Clear the checkbox for  the anonymous access. And now you can run your form with the forms server  happily ever after.

Important point:
 When you are using Forms Server with MOSS the site security is not applied to  the underlying services. It means even if your MOSS website requires  authentication, if Provider is anonymous enabled forms services uses anonymous  login for the external access, because it looks at the provider, not the site  that is hosting the form. It took me a long time to find it out because I had  the impression that Forms Server impersonates the user login information and  when I see the user ID on the top of my SharePoint page, this is not anonymous  call. I was wrong.

With special thanks to Infusion SharePoint Technical team  that gave me wonderful guides to resolve this issue.

There is no way to do this without writing code.  The two methods of  doing this with code are:

1. set up the connection as a Web service call to the lists web service on  SharePoint.  Use custom code in your form template to set the URL of the  Web service at runtime based on the URL the form was opened from, and then  execute the Web service connection.

2. When the form is hosted in the XmlFormView control, either in a client  application or on MOSS, you can set up your data connections to specify that a  portion of the serviceURL of the Web service can be dynamically replaced at  runtime.  This requires adding an element to the extensions section of  manifest.xsf:

•  

  Use the authoring tool published by the InfoPath team to create a UDC file.  After the file is created, upload it to a data connection library in your  SharePoint site collection or to the Manage Data Connection Files page in  Central Administration, whichever is applicable.

   
•  

  Add a data connection for the UDC file to your InfoPath form template. Use  the Connection Options dialog box in the Data Connection Wizard to choose  the way your form links to the UDC file.

   
•  

  Publish the form template to the SharePoint site collection. If the UDC file  is in a centrally managed connection library, you need to have administrator  rights to deploy your form template.
