When trying to join the MCU to an AD domain, it fails with the following error message:
"Active Directory verification failed because javax.security.auth.login.LoginException: could not obtain TGT"
The system the MCU was installed on was running java version 18.104.22.168. There is a known issue in any java version higher than 22.214.171.124 which causes the failure seen. This issue is documented in MCU defect ID #28628.
Downgrading java to version 126.96.36.199 resolves the issue.
