Enable StartTls new option is always TRUE in the UI, even if you try to uncheck it. But, it is properly persisted on disk
Same issue with version activedirectory 2.3
Yes, it is normal since it is not already merged.
On any case this is a minor issue, because:
1. StartTLS was always enabled by default
2. It is an UI issue, on disk is correctly saved.
Code changed in jenkins

[FIXED JENKINS-42831] should be default instead of checked
