With version 2 of the plugin, some major changes have been made internally. We have removed the deprecated ADAL4J library and replaced it with direct OIDC support. We also now query MS Graph instead of the deprecated AAD Graph for group membership sync. Additionally, logging has improved considerably to hopefully make errors easier to troubleshoot.
Possible Breaking Changes
For existing users, please note that with these changes there may be some issues with matching existing accounts. While effort has been taken to minimize these issues, it cannot be guaranteed that there is 100% compatibility. The switch from v1 to v2 logins on the Microsoft side changed a lot of the data this plugin relied on.
