Using Auth credentials with SPARQLStore VS SPARQLUpdateStore #755
Description
Hi, just a comment about something I discovered but can't quite explain.
I am trying to access a SPARQL endpoint which requires authentication, but for some reason the code below fails unless I substitute SPARQLStore with SPARQLUpdateStore.
Is that the expected behaviour?
In [1]: import rdflib
INFO:rdflib:RDFLib Version: 4.2.1
In [2]: g = rdflib.ConjunctiveGraph('SPARQLStore')
In [3]: g.store.setCredentials('my','password')
In [4]: sparql='http://graphdb/repositories/articles'
In [5]: g.open(sparql)
In [6]: g.query("select * where {?x a ?b} limit 10")
