ART MySQL 4.1 and default grants on PSA 8

[Hostasaurus@]

Hello everyone; I've upgraded a few RHEL 3 / PSA 8.0.1 servers from mysql 3 to ART's mysql 4.1 and since that time, all new users created via psa are given the grant:

GRANT SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES ON *.*

This of course is a bad thing because it lets any user create a mysql user that can see the names of all the databases on the server. PSA 8.0.1 on RHEL 4 where mysql 4.1 is standard are just given the default permission of:

GRANT USAGE ON *.*

Is this an issue with the art mysql 4.1, psa 8 on RHEL 3 or something else?

Thanks!
