Webmail - DB error: extension not found

[ryanz]

A new install of Plesk 7.5.4 on FC3 gives this error in the browser when trying to open Webmail

-------------------------------
A fatal error has occurred
DB Error: extension not found
Details have been logged for the administrator.
-------------------------------------------------

Where would these logs be as I don't see anything in /var/log/messages

What could be causing this?

Problem solved with this mysql command.

mysql> set password for some_user@localhost=old_password('the_password');

Also add old_passwords=1 to /etc/my.cnf

And restart mysql
