[keycloak-user] Request parameter in idp url

Need your help for some issue. I have configured an IDP in keycloak, i am sending a request parameter in single sign on url field in IDP as: url?ab=cd Issue i am facing is sometimes keycloak appends this parameter to the redirect url but sometimes it does not. Any idea as to why this is happening? Any help would be appreciated. Thanks in advance. Thanks, Pulkit
