There isn’t comprehensive WS support for external subjects in Grouper. This part is mainly so that Groupers can sync to other Groupers.

So make a group of external users somewhere, send a WS call to add a member to the group by EPPN or whatever, and set that flag to T, and it will add the external user. They could still login to the UI to register their personal information if you need it (that part isn’t part of the WS).

See the samples for addMember:

e.g.

POST /grouper-ws/servicesRest/v2_1_001/groups/aStem%3AaGroup/members HTTP/1.1

wsLiteObjectType=WsRestAddMemberLiteRequest&subjectId=external_user_id_here&groupName=aStem%3AaGroup& addExternalSubjectIfNotFound=T

Thanks,

Subject: [grouper-users] Attempting to add an "external subject" with Grouper REST API

I want to put an external subject into a Grouper group using the RESTful web services. The subject is identified by a Bamboo Person ID, which is just a value like

urn:uuid:e700afeb-daee-4d49-99ed-1753127e8985

The Grouper WS documentation on Add Member (https://spaces.internet2.edu/display/Grouper/Add+Member) has the following under "Features"

"You can specify addExternalSubjectIfNotFound to T or F, if this is a search by id or identifier, with no source, or the external source, and the subject is not found, then add an external subject (if the user is allowed to do this)"

I'm using Firefox Poster for a proof of concept, and wondering what to put in the request body to set addExternalSubjectIfNotFound to "T".

Advice welcome, --Keith

I made a WAG, tried the following and got errors:

----------

url: http://arche.metazome.info:8480/grouper-ws/servicesRest/v2_1_000/groups

content type: text/xml

POST

content:

<actAsSubjectId>GrouperSystem</actAsSubjectId>

</WsRestAddMemberLiteRequest>

----------

If I omit the line <addExternalSubjectifNotFound>T</addExternalSubjectIfNotFound>T</addExternalSubjectIfNotFound>

I get the expected "subject not found" error, since this subject is not available via any configured subject adapter

With that line in the request, I get this 500 error:
