To change a password in a ODBC in Windows, define this template in a child credential, so after the parent credential is changed, the password in ODBC will be changed too.
Create a new template, in the menu Executions > Settings > Templates :
Name: Windows - Change ODBC password
Executor: Windows RM
Execution Type: Password change
Content:
powerShell Set-OdbcDsn -Name “[#ADD_INFO#]” -SetPropertyValue@(“uid=[username#]”, “pwd=[#NEW_PASSWORD#]”)
