With the release of V6 we've expanded Social Connect to post directly to Linkedin company pages.
Connecting Linkedin Company Pages
Identical to our existing Facebook integration, connecting and posting to Linkedin company pages is accessed through personal profiles (administrator permissions).
Navigate to Social--->Manage Profiles. Select to add a Linkedin profile and insert your Linkedin credentials. Full walkthrough on connecting your social profiles found here.
If your Linkedin personal profile is an administrator on the company page, the page will be synced automatically with Social Connect.
To access your company page, select your personal profile image icon and select the company page--->done.
Now you’re ready to post!
