automysqlbackup: error 1044 database 'information_schema'

[Smallserver]

Hi all,

I get this error everyday:

mysqldump: Got error: 1044: Access denied for user 'root'@'localhost' to database 'information_schema' when using LOCK TABLES

This error comes from automysqlbackup wich I use for making daily backups of my databases.

I've searched the internet but all I can find are old postings regarding an old bug in mysql. Since I use the latest version (server is a 2 month old install) that can not be the issue. I've had this error from day one, but not on the former installation.

Any hints?

Thanks,
Herman
