rember: usersec hash on upgrade

[ascii]

i just wanted to share it with you.

if you do change the hashing string in inc/libmisc.pm  in the XORpass function.
remember to also change it after the upgrade.
the upgrades overwrites the file and NeDi will send the wrong password.
i ended up with a locked AD account for my backup and was wondering how that could happen.

Very good point. In newer versions, you'll have to do the same to libmisc.php.

The price of more security
