Currently the LDAP store configuration forces users to provide the supported types as follows:

.ldap()
    .supportType(Agent.class) // redundant supported type configuration
    .mapping(Agent.class)
    .objectClasses("account")
    .attribute("loginName", UID, true)
    .readOnlyAttribute("createdDate", CREATE_TIMESTAMP)

We can simplify the configuration by discovering all supported types from the mapping configuration, as follows:

.ldap()
.mapping(Agent.class) // the Agent type is automatically added to the lit of supported types
.objectClasses("account")
.attribute("loginName", UID, true)
.readOnlyAttribute("createdDate", CREATE_TIMESTAMP)
