With IDM disabled, OBM is integrated with Operations Orchestration (OO) and working as expected, ie launching runbooks from OBM event perspective opens OO without requesting username/password. After enabling IDM on OBM, the runbooks launch from OBM always requires username/password to access OO.

Environment

All supported OBM and OO versions.

Situation

After enabling IDM on OBM, the runbooks launch from OBM always requires username/password to access OO.
The TOPAZ_HOME\log\webapps\oo_integration.log on the Gateway shows the following error:
