when doing a scheduled Virtual Server backup I get the following error for every MySQL database:
Dumping MySQL database foo .. .. dump failed! mysqldump: Got error: 1045: Access denied for user 'debian-sys-maint'@'localhost' (using password: YES) when trying to connect
System is a standard Debian 5.0. The MySQL login using credentials from /etc/mysql/debian.cnf is working fine at the Shell. Also using user root and the password as seen in Webmin > Servers > MySQL Database Server > Change Administration Password is working.
Any hints where to get more information/solution for this error?
