passwords

It is possible to define a technical user in the environment, which has higher priority than the technical user defined in hos_config2.php. But the environment is stored in a cache when a process is interrupted (the credentials are safely encoded). When the password changes during the time the process is interrupted then the one in the cache is no more valid, which causes failures when the process is opened again. This can be easily solved by passwords option. Password coded here has even higher priority than the one stored in the cache. For this reason if you change a password of your technical user then you should also set it here.
