With SAML-tracer I’m see a GET hitting the SAML endpoint configured as SAML login url in the edit SAML configuration window. I do see PUT’s hitting other Okta apps.

My question is: Is the lack of a POST request hitting the SAML login url my problem? If so, how do I ensure that Okta is using POST instead of GET?

Hi,

Welcome to the community!

My searches indicate that the lack of the POST probably is the problem. It looks like you should make sure the SonarQube side is fully configured.

 
HTH,

Doesn’t this insinuate that the SonarQube side is fully configured?

Hi,

Was that a snippet of your SonarQube log that you provided? If so, can you provide the whole log?

 
Thx,

We got this resolved. However, this brings up an issue that I’m not sure is covered by a pre-existing Feature Request: We need to provision users manually with our Dev license. However, once we setup the user we need to make API request (update_identity_provider) to convert the user from local auth to SAML auth. This is not documented here.

  1. Is there an existing Feature Request to either automate this or include it in the UI?
  2. Can the documentation be updated to be clearer?

Hi,

Can you explain why you need to provision the users? Can’t you just let them be created on first login?
