Description:

Store your UNIX user accounts in MySQL. "libnss-mysql" enables the following:

* System-wide authentication and name service using a MySQL database.
Applications do not need to be MySQL-aware or modified in any way.

* Storing authentication information in a database instead of text files.

* Creation of a single authentication database for multiple servers.
This is often referred to as the "Single Sign-on" problem.

* Writing data-modification routines (IE self-management web interface).

libnss-mysql is similar to NIS or LDAP. It provides the same centralized
authentication service through a database. What does this mean? Username,
uid, gid, password, etc comes from a MySQL database instead of
/etc/password, /etc/shadow, and /etc/group. A user configured in MySQL will
look and behave just like a user configured in /etc/passwd. Your
applications such as ls, finger, sendmail, qmail, exim, postfix, proftpd,
X, sshd, etc. will all 'see' these users!
