On a webserver there is a MySQL-service running, providing databases for the users of the server. Each user has it's own DB and it's own password and the right so INSERT/SELECT/UPDATE/DROP tables in it's own DB, but nothing more.
However, i want to give the user the privilege to UPDATE his own password. I've read "184.108.40.206. GRANT Syntax" from the MySQL 5.1 documentation. But i didn't found a way to grant the user the privilege to change his password, without granting full UPDATE-access to the mysql.user-table.
Maybe there is also a way to synchronize the passwords in /etc/shadow along with the passwords in mysql.user, so, each time when the user changes his password in Linux, the MySQL-password is also altered.
