Memory leak when using SASLLogin

[opensprinklershop]

When you set setSASLLogin( true ); a memory leak opens:
The cause is, there is a malloc( size ) , but no free:

	  if (this->isSASLLogin == true){

		  int size = 1 + strlen(this->email_login)+ strlen(this->email_password)+2;
	      char * logPass = (char *) malloc(size);
....
  }
}
