When you are using two use stores, you need to map the attributes correctly using claim management. Under "Mapped Attribute (s)" you need to follow the pattern....
{domain_name/attribute_Name};{domain_name/attribute_Name}; {domain_name/attribute_Name};
and so on.. But for default user store, you do not want to provide the domain name. As an example, if you have two user stores, one is default and other one with domain "LDAP" then patter would be as follows for http://wso2.org/claims/emailaddress
email;LDAP/mail
