If you delete the user, the sasl functionality won't work anymore. This 
may create issues with authentication in KDE.

So... DON'T delete the user.

Note that the password is not set so that nobody can log in as this 
user... so it does't pose a security risk... There are serveral other 
users like this... daemon, operator, games, postfix, named, ntpd, sshd, 
uucp, www (www if you install Apache)... They don't create security risks.

perhaps that is too much to ask for.

It appears that cyrus-sasl was installed as a dependency when I
