Lync and the "Cannot Generate SSPI Context" error

If you have this error, it is probable a Kerberos issue. Try to set the SPN of you SQL Service Account.

  1. Find out which user runs the SQL Service on your database server.
  2. Find out the port (Standard 1433)
  3. FQDN of the database server
  4. Use SetSpn -a MSSQLSvc/NX5015.swiss.group4net.com:1433

Reference:
"Cannot Generate SSPI Context" error message, Poisoned DNS on MSDN

Open SharePoint 2010/2013 Display, Edit, New Forms in Modal Dialogs

This is easy to configure but redirects only the site in which the WebPart sits (Probably the Mainsite).
