Yes, we are trying to use sqlAlchemy over psycopg2. However, my experiments have been on standalone psycopg2. Because I
wasworking back and forth, I took the wrong connection string.
Here's the exact string that I'm using in stand-alone psycopg2:
1. conn_string = "host=fqdn_hostname' dbname='dbname' krbsrvname='postgres'"
or
2. conn_string = "host=fqdn_hostname' dbname='dbname'"
The 1 gives the error of: psycopg2.OperationalError: invalid connection option "krbsrvname"
The 2 gives the error of: psycopg2.OperationalError: GSSAPI authentication not supported
Sorry for the earlier confusion.
Thanks.

It would have been nice to know you where using SQLAlchemy above
psycopg2 at the beginning of this conversation.
So again can you show the actual complete string you are using?
Not sure if this a cut and paste error but you have:
? krbsrvname=postgres
Pretty sure the space between ? and krbsrvname is not good.
Also what happens if you bypass SQLAlchemy and try to connect using
psycopg2 directly?
