Hi In the KeyCloak configuration under User Federation i have defined a User Federation Mapper which has a mobileMapper which maps mobile number from LDAP under user Attribute in key Cloak. Below is the configutaion. UserFederation-->UserFederationMapper-->mobileMapper User Model Attribute=mobile LDAP Attribute=mobile Always Read Value From LDAP=true The mobile number is not coming in the attribute object automatically while the other attributes are coming automatically like email ID,name and userName in the attributes object under UserRepresentation How do i get mobile number automatically in the org.keycloak.representations .idm.UserRepresentation attributes object. Key Cloak Version is 2.1.0 final Regards, Vikash
