Line feed delimited multi-value attribute

[Bryan Wooten]

Ok, let's review what I am trying to do.

I have a existing OpenDJ multi value attribute we call uuenroll.

It looks like this when I cut and paste from Softterra:

uuenrl: Fall 2016$1181$CS$3500$001$LEC$Software Practice$4$1
uuenrl: Fall 2016$1722$CS$3500$002$DIS$Software Practice$0$2
uuenrl: Fall 2016$1182$CS$3810$001$LEC$Computer Organization$4$3
uuenrl: Fall 2016$9694$GERM$2010$001$LEC$Intrm German I$4$4

They want this:

FA16:CS:3500:001

We send this:

I wrote this Script:

          eduCourseOfferingTemp.getValues().add(uuenrl.getValues());
          var courses = "";

          ]]></Script>

 </resolver:AttributeDefinition>



That is a lot of detail.

Bottom line is this line:


eduCourseOffering.getValues().add(courses);

How can I change it to MAKE the add do Line delimitation?

Yeah is it crap code, sorry first time doing a Script. Still trying to learn.

I think there's some confusion here over what you're doing and they're doing. There are no commas or linefeeds. Multiple values are just that, separate. You are NOT making them comma delimited. I don't know what you're seeing that makes you think that, but I would be surprised. Your logs should show it clearly either way.

Any "delimiter" is something they're inferring from their software, I think, and for the record, we use eduPersonEntitlement to carry that same value set to them, and I pass them in the normal way, separate values in SAML. They handle it fine.
