security authentication API via solrj?

[Peter Sturge]

Hi,
I was wondering if 7.2.1 solrj had native support for the
security/authentication endpoint? I couldn't find anything in the docs
about it, but maybe someone has some experience with it?
Note: This is about adding/deleting users on a solr instance using solrj,
not authenticating (that is well documented).
Thanks,
Peter
