Database connection: proxy in front of solr

[xueyun0512]

Bug description

Hello,
I want to connect to Apache Solr. However, since I have configured Solr to use Kerberos, I can't connect to the Solr server directly (as solr-sqlalchemy does not support Kerberos authentication protocol).
Therefore, I have set an proxy in front of Solr. I'm using Knox Gateway.

When I tried the following URi
solr://username:password@my.knox.vip.com:443/europe-italy/team-tiramisu/solr/cheese_collection

Where:
443: port
europe-italy/team-tiramisu: knox gateway topology
cheese_collection: my Solr collection name

I got the error:
ERROR: Expecting value: line 1 column 1 (char 0)

Can you help me please?

In this case, what is the easiest solution?

1. Change the source code solr-sqlalchemy to support Kerberos?
2. Change the source code solr-sqlalchemy to use Knox Gateway ?
