We're deploying a COM+ application as an MSI and then trying to modify the application catalogue to use a non-system user (which requires a username and password). A delta package created from the resultant configuration change fails to deploy with the following message:
"The identity or password set on the application is not valid."
When we created the delta package, it only seemed to detect the user name and not any configuration changes regarding the password, so we're not sure how to proceed from here. OpsMgr seems to have an interface to enter password confirmations for some areas, but it doesn't seem to be active for this node (the "Identity" property for a COM+ application).
