5.0.77 - how to activate federated?

I've read the documentation and checked the forums but still am unable to get federated working on MySQL 5.0.77 (specifically, mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i386) using readline 5.1).


I added the following line to the [mysqld] section of /etc/my.cnf:
federated=1

I added --federated to the startup options for mysqld. Here are the active running processes:

# ps -ef | grep mysqld
root 2456 1 0 11:30 pts/0 00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --socket=/var/lib/mysql/mysql.sock --log-error=/var/log/mysqld.log --pid-file=/var/run/mysqld/mysqld.pid --user=mysql --federated
mysql 2511 2456 0 11:30 pts/0 00:00:00 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run/mysqld/mysqld.pid --skip-external-locking --socket=/var/lib/mysql/mysql.sock --federated

However, it appears that federated is still not available:

mysql> show engines;

| MEMORY | YES | Hash based, stored in memory, useful for temporary tables |
| InnoDB | YES | Supports transactions, row-level locking, and foreign keys |
| BerkeleyDB | YES | Supports transactions and page-level locking |

| ISAM | NO | Obsolete storage engine |
+------------+---------+----------------------------------------------------------------+
12 rows in set (0.00 sec)

So, I need some guidance on what else needs to be done.

Thanks in advance.
