I would like to know if it would be an alternative solution to the problem of invalid_credentials in dynamics data actions ?
Our instance of Dynamics is using another authentication form for Single Sign On. AD syncs with a local AD. When we log in to CRM we actually go to another login method which issues a SAML token.
it seems that the problem was discussed before in this thread below :
How can we proceed to authenticate correctly the data actions ?
Can you use the same solution that was used in the thread you referenced, create a stand alone user for the Dynamics Data Actions to authenticate with?
If that is not an option then you would need to look into creating a "User Defined (OAuth) credential type and custom auth action to handle getting the SAML token"
I do not know exactly which solution is the best. I would like to authenticate my data actions since there is an STS authentication mechanism because we are using a local AD.
I don't know anything about that authentication system. Are you able to perform the authentication steps in a tool like Postman? Assuming it is a "Make one call to get a token" and then "Include that token in future requests" sort of system it will likely be something you can implement with data actions once you have worked out the details manually.
