check passwords in the dictionary works in Plesk 8.2 but not work in 8.6

[nethubonline]

Hi all,

We have servers that are running Linux Plesk 8.2 and 8.6 versions, we checked "Check the passwords for mailboxes in the dictionary" works fine in Plesk 8.2, it can prevent user to set the password to simple password such as "modem", however it doesn't work in Plesk 8.6.

We double checked the database psa.misc, the value of "use_vocabulary" is true and the default dictionary files still exists

/usr/local/psa/etc/dict.hwm
/usr/local/psa/etc/dict.pwd
/usr/local/psa/etc/dict.pwi

We wonder it works in version 8.2 but not work any more in 8.6, is this a known issue? How can it be fixed?

OS: both servers are running RHEL 5.2
