[keycloak-user] Keycloak username attribute

[Steve Munene]

Hi, what is the saml user attribute used by keycloak in the saml response.

I keep getting this when after login from cloudstack
<loginresponse cloud-stack-version="4.10.0.0<http://4.10.0.0>">
<errorcode>531</errorcode>
<errortext>
Failed to find admin configured username attribute in the SAML Response. Please ask your administrator to check SAML user attribute name.
