Error connecting to AAA STS for RDP access - username correct but suspecting URL migration from T...

...R to Refinitiv is the cause

Hi

We are integrating with AAA retrieving the STS token for access to RDP streaming pricing. Until recently we have been successfully authenticating from the existing Thomson Reuters URL https://sts.login.cp.thomsonreuters.net/

Two weeks ago we tried to connect a new users on production with AAA. However when they use the above URL they get an error

2021-08-05 13:12:17.970 DEBUG SerializableWebMessageBase: {"BaseUri":https://sts.login.cp.thomsonreuters.net/,"ClientId":"*******","ClientSecret":"*****","RequestID":"1","HttpStatus":200,"UseJsonSerialization":true} Subject: SerializableAAAClient

2021-08-05 13:12:20.681 DEBUG {"error": "access_denied", "error_description": "Invalid username or password."}

We have tested the same credentials on:

- User's Eikon login = successful

- RDP playground = successful

We think this maybe due to the migration in domains. Is that correct? Could there be another cause for the failure to login and receive the STS token?

If the issue is the Domain, could someone confirm the correct URL is identity.ciam.refinitiv.net and when was this change expected to be made?

Thank you,

Nick
