After upgrading to 14.4 Identity Manager would not start unless we specify the Username and Password in the /standalone/configuration/standalone full xml instead of the Security Realms
Release : 14.4
Upgrade did not fully update the <appserver>/modules folder.
Please pull the
folders from a fresh install of 14.4, and place that into the respective folders on the problem system and restart.
Once the startup is confirmed to work you can return to using the security realms in the standalone xml file.
If there is not a fresh installation of 14.4 to pull the modules folder from, please reach out to the Broadcom Support team.
