The KB article at https://support.quest.com/de-de/identity-manager/kb/121520 describes how to encrypt connection strings for deployment.
How can this be used with SystemDebugger.exe?
If using a commercial version of Visual Studio or the community edition of 2013 or later, it is possible to change the start action for the project SystemDebugger by selecting Properties | Debug.
Select "Start External Program" and navigate to SystemDebugger.Oracle.exe beneath Debug\bin.
Despite the name, the binary is not limited to Oracle connections but can also connect to Microsoft SQL Server. The binary is precompiled and can read [C]-encrypted connection strings from registry or global.cfg.
Enhancement Number 23276 has been created to ship a binary with D1IM instead, this may be implemented in a future version of D1IM.
