Is it possible, in Blackboard Learn or Saas, to "LTI" into Blackboard from another system? In this instance, the other system would be an LTI Consumer, and Blackboard would be the LTI Provider.
No, Learn is just a tool consumer, not a tool provider.
If you are just looking for a simple way to SSO into Learn, then there is a building block that provided incoming SSO using a shared secret. See AutoSignOn Building Block
