OpenLDAP + Samba Domain Controller On Ubuntu 7.10

This document is a step by step guide for configuring Ubuntu 7.10 as
a Samba Domain Controller with an LDAP backend (OpenLDAP). The point is
to configure a server that can be comparable, from a central
authentication point of view, to a Windows Server 2003 Domain
Controller. The end result will be a server with an LDAP directory for
storing user, group, and computer accounts. A Windows XP Professional
SP2 workstation will be able to join the domain once properly
configured.

Reset the root password on MySQL

MySQL is a relational database management system (RDBMS) based on SQL (Structured Query Language). First released in January, 1998, MySQL is now one component of parent company MySQL AB’s product line of database servers and development tools.

Yes, it really is this easy.run the following command to change the mysql root password

sudo /etc/init.d/mysql reset-password
New MySQL root password:
Verify:
Setting new MySQL root password

But how? Debian (and by inheritance, Ubuntu) have a special user called ‘debian-sys-maint’ on each mysql install that has admin privileges on the server. It’s used to shutdown the server gracefully, automatically check for corrupt tables, and resetting your password. Its password is randomly generated, and stored in /etc/mysql/debian.cnf. Handy if you want to do some admin scripts yourself.
