I assume that you want to know what observations belong to what 
cluster?  Then I think the "clustering" element of the returned object 
holds that information.  If you want the information in a different 
form, you will have to do a bit more work.  As an example, to find all 
the observations in the first cluster, you could do simply:

first.clust <- which(my.clara.object$clustering==1)

Does that give you the type of information you want?
