Iridiumserver password with "special" characters

During intial setup of my first Iridium UMC server I ran into trouble after setting the password.

After that I always got the "wrong password" error when logging in.

With some trial&error I found out that there is a problem with passwords with special characters.

At least passwords with ^ and & give problems.

Please fix this bug, or make sure that the user cannot set password with forbidden characters in the first place.
