Create SQL Alchemy connection string using Okta IdP

Problem description

import redshift_connector

# An Okta auth page will pop up when initiating this connector
conn = redshift_connector.connect(
    host='<cluster_identifier>.ap-southeast-2.redshift.amazonaws.com',
    port=5439,
    region='ap-southeast-2',
    database='<db_name>',
    credentials_provider='BrowserSamlCredentialsProvider',
    login_url='<saml_url>',
    cluster_identifier='<cluster_identifer',
    preferred_role='arn:aws:iam::<iam-id>:role/<role-name>',
    user='',        # left empty string
    password='',    # left empty string
    iam=True,
    ssl=True
 )

cursor: redshift_connector.Cursor = conn.cursor()

Currently, I can connect to Redshift using the above credentials but when trying to utilise the SQL Alchemy connection string - it causes an identification error (using sqlalchemy-redshift). Is there a way to generate an appropriate URL for sqlalchemy to parse for IdP authentication?

I’ve noticed that Redshift was recently updated to work with sqlalchemy-redshift but have had no luck generating an appropriate URL login.

Hi @Brooke-white, did a fresh install this morning and tried. Looks like everything is working perfectly. Closing the thread. The debug logging helped me iron out any issues. Thank you again for your help and patience on this!
