$attributes = @ldap_get_attributes($this->connection, $this->firstResultEntry); may return FALSE on array. In this case the following foreach loop will trigger a warning/error.
In the flow of the code it may be the case that $this->firstResultEntry is FALSE. In other other parts of the code there is some protection: is_resource($this->firstResultEntry).
Sidenote: It is not clear to me why $this->status['get_first_entry']['status'] = ldap_error($this->connection); is executed as the very first statement in the function.
