There is not an official, supported integration between CA Agile Central and Sharepoint. There are some unsupported tools out there that provide a one-way integration, just displaying Agile Central information on Sharepoint, but no bi-directional integrations that I know of. Someone else on this Community may have something they have done, however.
I removed the link in the other post to avoid confusion.
If anyone else has experience or a working integration, please let Bob know.
