I am trying to add SAML authentication by referring the following doc.  
[https://www.elastic.co/guide/en/kibana/current/kibana-authentication.html#saml](https://www.elastic.co/guide/en/kibana/current/kibana-authentication.html#saml)  
I added the configs to the kibana.yml and start kibana server. Then it prompts an error like this.  
`ValidationError: child "xpack" fails because [child "security" fails because ["authc" is not allowed]]`  
I have the trial licence and I am using the elastic stack 7.0.1. Could anyone can point me to a solution for this?

Hi,

You are using the instructions for the current version (7.7) and try to apply them on a rather old and unsupported version. Why don't you download 7.7 and start over ? 🙂

Hi,

Sorry about that mistake. By the way this is the 7.x document. [https://www.elastic.co/guide/en/kibana/7.x/kibana-authentication.html#saml](https://www.elastic.co/guide/en/kibana/7.x/kibana-authentication.html#saml).  
As far as I can see there is no any differences in both these docs. Please correct me if I am wrong.  
Thanks.

7.x doesn't mean "any minor version in 7" but "the current (unreleased) minor in 7".

```auto
xpack.security.authc.

```

was not available in 7.0.x and this is why you get an error.

Please follow my suggestion above
