query members by source(s)

You should be able to query members of a group by sourceId(s) of the members.

You can do this with the API e.g.:

public Set<Member> getMembers(Field f, Set<Source> sources, QueryOptions queryOptions)

You can do this with WS:

String[] sourceIds (on getMembers and getMembersLite (on lite it is a comma separated string))

On grouper client:

--operation=getMembersWs --groupNames=aStem:aGroup,aStem:aGroup2 --sourceIds=jdbc,g:gsa
