Cannot edit document using SharePoint2010 Claim Based site

Hi,

  Purchased license for Adobe Acrobat X Pro. User should able to edit the pdf document using Adobe Acrobat X pro.

Adobe Acrobat X Pro should be opened by clicking the link "Edit Document" into "MS SharePoint2010 site collection" with "Claim Based authentication".

Adobe Acrobat X Pro opens successfully, but it does not open pdf file. Error is displayed as-

"There was error opening this document. The filename, directory name, volume label syntax is incorrect".

When request response from adobe acrobat to sharepoint 2010 is checked, sharepoint server respond with 302 http code. This code trying to force adobe acrobat to re-authenticate. Can some help to solve this?

thanks
