If we configure Global Proxy (Configurations -> Configure Global Proxy), the password set is saved in clear text in IM_ENVIRONMENT_JDBC_LD -> SECTION_NAME = 'misc'.
IDM 14.5
It is working as designed
We validated this issue, and it is a known one; the password saved will not be encrypted. The Behaviour is the same in the V15.0 version too, but we are planning to address it in the next fixpack release.
