Method not supported when SAML auth is configured about onpremises HOT 14 CLOSED

ok, so figured out what was the issue in our case. I set the Azure Enterprise App application id as entityId, instead I should ofcourse have used the Entity Id. Strange to get a 405 on this. I also noticed that the return url is case sensitive, so redirecting doesn't work if the url's don't match case

Your case may have been already solved by issue #8.

You have to adjust structurizr.saml.maxAuthenticationAge property to higher (90 days ?) than the default value (2 hours): https://structurizr.com/share/18571/documentation#max-authentication-age

Thank you for the screenshot, i fixed it now :)

Issue (for me) was that i disabled "sign document" function. Just in case if anyone need, sending my KC screenshot of the working configuration:

That's great, thanks. Would you consider sending a PR for the docs please?

Thanks @samm-git that was also a problem on my side. Once I enabled SAML signed request then it started to work. BTW, to do that I had to export cert from jks existing on repo for structurizr onprem and upload it to Okta so then it was possible to enable it.

Hi people, i face the same problem with Azure AD and I resolved creating group claim on Enterprise Application:

from onpremises.

we are running into the same issue. Our configuration looks pretty similar to the OP's, we are also getting a 405 Method not allowed on the /saml/sso endpoint. In the logs we see the following error:

DefaultHandlerExceptionResolver - Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' not supported

but for completeness sake:

• our Structurizr app is running in an Azure Appservice
• version 3040
• we created an AAD Enterprise Application with return url {my-app-name}/saml/sso (where {my-app-name} is a placeholder for our real app name of course)
• added the structurizr.properties and saml-idp-metadata.xml files and restarted the appservice

structurizr.properties:

structurizr.authentication=saml
structurizr.url=https://{my-app-name}.azurewebsites.net
structurizr.saml.entityId={client id of the AAD Enterprise Application}

from onpremises.

Same problem wit keycloak here. Already tried to change the max-authentication-age to 8h, 24h, and 90 days, and didn't worked.

Same on my side, KC+structurizr

Somebody on the Slack group (onpremises channel) has mentioned that the instructions for Keycloak are out of date, and posted an updated screenshot. You may want to jump on there and take a look.

Alternatively, you may want to try forcing authentication -> https://structurizr.com/share/18571/documentation#force-authentication (although this seems to be related to issues with Azure AD).

Done, #47

Have similar problem when integrating with Okta. I receive on server logs
DefaultHandlerExceptionResolver - Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' not supported].
This is on the returning from already authenticated user on /saml/SSO

Did anyone resolved that problem? why structurizr is not accepting POST on that url.

from onpremises.

In my case it was disabled signing on the request, please check your settings.

Closing since the OP hasn't responded, so I'm assuming this is resolved ... please open new issues/discussions as needed.
