Legacy authentication type removed

Blackboard Learn 9.1 Q4 2019

When Blackboard introduced the extensible authentication framework long ago, our main authentication moved to the Default type. We retained the previous framework as Legacy to support older custom authentication types, but have since deprecated it. With this release, we’ve removed the deprecated and unsupported Legacy authentication type from the Administrator Panel > Authentication. Custom authentications should use the extensible authentication framework instead.

Administrators should confirm that the legacy authentication type is disabled prior to upgrading so it can be removed by the installer. If it is enabled, the installer will stop and request legacy authentication type is disabled before restarting the installer.
