Connection to contentdistributor could not be validated

When configuring SharePoint to use FAST Search Server, you recieve errors when running SecureFASTSearchConnector.ps1:

This problem can occur if the SSL certificates that were installed with FAST Search are expired or invalid. This problem can also occur if the Content Distributor port specified when configuring the "Fast Connector SSA" was not correct.

Scenario 1:

There are many SSL certificate scenarios that could cause connectivity issues between SharePoint and FAST Search, in some cases recreating new certificates and reconfiguring security with the ReplaceDefaultCertificate.ps1 and SecureFASTSearchConnector.ps1 scripts, is the best method to resolve this issue.

Please see the product documentation on certificate management (http://technet.microsoft.com/en-us/library/ff381244.aspx) for more information.

Additionally the certificate may not be validated if the user specified for SecureFASTSearchConnector.ps1 is not the user running the "SharePoint Server Search 14" service, or if the DOMAIN\COMPUTERNAME of the Search 14 service is not added to the local group FASTSearchAdministrators on the contentdistributor FAST Search servers.


Scenario 2:

The “Fast Connector SSA” may be incorrectly configured to use port 13390. The %FASTSEARCH%\install_info.txt" displays the Content Distributors with port "13391", however the %FASTSEARCH%\etc\contentdistributor.cfg" displays port 13390. If the port for the "Content Distributors" in the “Fast Connector SSA” was configured as "13390", connectivity to FAST will fail. If this is the case, the "Content Distributors" in the “Fast Connector SSA” should be reconfigured to use port 13391 as stated in the install_info.txt.

The the install_info.txt and the contentdistributor.cfg list different ports by design. Port 13390 is for non-secure communications to the Content Distributors that is utilized by internal FAST communications only. However, 13391 is used for secure communications to the Content Distributors, which is required when connecting from SharePoint.
