Here is the string I am using 'UPDATE virtual_users SET
password=ENCRYPT(%p,concat('$6$',substring(sha(rand()),-16))), WHERE
email=%u LIMIT 1';

However, now roundcube is crashing and I am seeing this error

[06-Mar-2017 22:30:32 America/New_York] PHP Parse error:  syntax error,
unexpected '$' in
/var/www/roundcube/roundcubemail-1.2.1/plugins/password/config.inc.php on
line 106

Not sure what I am missing....
