Loading new clients without a restart

[Clayton Knorr]

Suppose you're loading your clients in from LDAP or SQL, and you need adding new clients to be relatively dynamic. Reloads don't pull in the clients, just restarts. I assume other people have run into this issue and didn’t want to restart Freeradius once a day or more just to load a new client. Are there some clever solutions out there anybody has come up with? Or a super secret feature I don't know about?
