[Walter2]

Hello Guys,

We are having problems trying to log in via SSO to Dynatrace, we started yesterday and the message I am receiving is this:

AADSTS900561: The endpoint only accepts POST requests. Received a GET request.

Hi @Walter2 

1. check the communications between the cluster nodes and the ADFS.
2. On ADFS side ensure the proper setup for ADFS
3. SAML ADFS 
4. after proper preparation 
5. On DT Side > Download XML metadata of a SAML 2.0 Service Provider.
6. Share it with ADFS team.
7. Then will follow Dynatrace documentation to get the final XML metadata of a SAML 2.0 Identity Provider which will be uploaded through CMC.
8. Upload the XML metadata of a SAML 2.0 Identity Provider.
9. save and check how SSO is working.
