Hi,  
I’m switching from the LDAP to SAML authentication and getting this error message:  
Authentication failed: SAML login failed: [‘invalid\_response’] (The response was received at [https://awxurl:8052/sso/complete/saml/](https://awxurl:8052/sso/complete/saml/) instead of [https://awxurl/sso/complete/saml/](https://awxurl/sso/complete/saml/)).

Looks like docker’s container port is getting appended to the URL.

Does anyone know how to fix it?

Regards,  
Larry

Looks like the same question here: [https://groups.google.com/forum/#!searchin/awx-project/saml$208052%7Csort:date/awx-project/aQTtlsm6Zlc/f7R8ePlJBAAJ](https://groups.google.com/forum/#!searchin/awx-project/saml$208052%7Csort:date/awx-project/aQTtlsm6Zlc/f7R8ePlJBAAJ)  
and never was answered… I also use nginx for SSL part.

Got it to work using this post: [https://github.com/ansible/awx/issues/1016](https://github.com/ansible/awx/issues/1016)

Just in case If anyone needs it: I’m running AWX 4.0.0 in the docker containers. In my case it was enough to add one missing parameter to the proxy configuration:

`

```auto
proxy_set_header X-Forwarded-Port 443;

```

We had fixed the same via F5 load balancer.
