Profile Attributes Processing - Map Key

I have a customer who asked me whether the same Map Key can be mapped to multiple Corresponding Map Value. This is regarding Profile Attribute Processing for Policy Agent configuration.

He wants to map UID from data source to USERNAME and EMPLOYMENTID. This is part of his application team's requirement during Policy Agent integration.

I tested in our test environment. Not possible.

The OpenAM debug log will throw the following stack trace:

ERROR: AgentsRepo.setAttributes(): Unable to set agent attributes

I checked the attribute in the embedded configuration store (OpenDJ). It should be able to handle same Map Key be mapped to multiple Corresponding Map Value scenario.

There is no error found in OpenDJ access log as well.

So this must be a feature. I suppose.
