Authenticate Between Work.com and Other Orgs
If Work.com has been installed in a new, dedicated org, but your solution must access
the original org, you need a strategy for authenticating to the other org.
The following are recommended strategies for authenticating to another org.
Use the existing, original org as an identity provider. Use user authentication from the original org to log in to the Work.com org. Avoid creating replicated logins in the new Work.com org.
If the existing org is already using a different identity provider, you can either connect the Work.com org to the same identity provider, or connect the Work.com org to the existing org.
