Test SAM db server with Kerberos authentication to the database
[Originally JIRA SAMDEV-63]
We need to test whether the SAM db servers will work correctly with Oracle Kerberos authentication.
This requires using a suitable version of the oracle client libraries, and passing the appropriate connection string to the DB. I don't believe cx_Oracle needs any changes.
We should test this out on the development system. The DBAs will have to provide a suitable Oracle account which uses Kerberos.
