I didn't understand what happened. But after reinstalling Virtuoso, it's
been working. Thank you anyway.
Best regards,

Hi everybody,
I am a newbie with Virtuoso. I am working in a system where we need to
support SPARQL queries and some kinds of privacy.
I suppose that I have three graphs:
- http://example.com/public (anybody can have READ access to this graph)
- http://example.com/private/Anna (only Anna has READ access to this
graph)
- http://example.com/private/Bob (only Bob has READ access to this graph)
I was trying as the following steps with dba (only the 'dba' user can
update data):
DB.DBA.USER_CREATE ('Anna', 'Anna');
DB.DBA.USER_CREATE ('Bob', 'Bob');
DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('nobody', 0);
DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('Anna', 0);
DB.DBA.RDF_DEFAULT_USER_PERMS_SET ('Bob', 0);
DB.DBA.RDF_GRAPH_USER_PERMS_SET ('http://example.com/private/Anna', 'Anna', 1);
DB.DBA.RDF_GRAPH_USER_PERMS_SET ('http://example.com/private/Bob', 'Bob', 1);
When I executed those commands, I received errors saying
Permissions of unauthenticated user are broader than new permissions of user Anna on
specific graphhttp://example.com/private/Anna. This kind of message also happened for
'Bob' user.
I was wondering if someone could tell me where I was wrong or what I had to do
to fix this issue. Thanks in advance!
Best regards,
Kinh
