Hi All,  
For SAML configuration, what parameter to be used instead of persistent,  
attributes.principal: "nameid:persistent"

In Azure it is 'unspecified' or emailaddress

You can use `attributes.principal: nameid` ,this is also covered in our [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/master/saml-guide-authentication.html#saml-attribute-mapping-nameid)

Thanks @ikakavas.  
I tried with attributes.principal: "nameid" but didnt worked.  
So i Used : attributes.principal: "[http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name](http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name)"

Browser Asks to save SAML response.

F12 Developer Tools -  
Response Body -  
{"statusCode":401,"error":"Unauthorized","message":"[security\_exception] unable to authenticate user [] for action [cluster:admin/xpack/security/saml/authenticate], with { header={ WWW-Authenticate={ 0="Bearer realm=\"security\"" & 1="ApiKey" & 2="Basic realm=\"security\" charset=\"UTF-8\"" } } }"}

ES Logs :  
"[WARN][o.e.x.s.a.AuthenticationService] [SA145] Authentication to realm saml1 failed - Provided SAML response is not valid for realm saml/saml1 (Caused by ElasticsearchSecurityException[SAML content is in-response-to \_afe391812ba357beef3a6c11113b8b80f4bbd1c5 but expected one of])"

Not getting whats going wrong here here.
