MySQL 5.5 Authentication Goodies

MySQL 5.5 is currently in the Release Candidate phase and making good
progress on the way to being a Generally Available release. There
are many new features that will improve performance, make service
more robust, and generally make life better for DBAs. But since
5.5.7 was released for evaluation in October, there has not been a
lot of attention given to the changes in authentication.

To greatly simplify, MySQL has a table with a list of users and a
list of hosts from which those users are allowed access. So user
'jones' and the host they connect from are checked to make sure they
are allowed access. If they match, they can access the instance.

As of 5.5.7, MySQL authentication now supports pluggable
authentication and proxies. So now you can use PAM, Windows native
authentication, LDAP, or something similar to control user accounts.
Or use proxies for group of users. For example user 'smith' is in the
'programmer' group in the LDAP directory. But there is no entry in
the MySQL.user table for that user. The server will now use the
pluggable authentication to reference an outside authentication
service to determine the group. The connection will be established
with the USER() set to 'smith@host' and CURRENT_USER() set to
'programmer@%'. Please refer to for details.
