RE: FreeRADIUS + LDAP Authentication/Authorization + MySQL Accounting

-Authentication through LDAP

YES. Using it currently !

-Authorization through LDAP

YES. See above :)

-Accounting through MySQL

YES. Doing traffic accounting.  

I have multiple Cisco and Foundry devices on my network.  The RADIUS server will primarily be used for AAA for Telnet/SSH logins and eventually VPN dialin accounts.  Is FreeRADIUS the software I should use?

RADIUS provides AAA features and freeRADIUS is just one hell of a software :) I am using ProCurve with RADIUS support and I didnt have any troubles setting it up. ProCurve is based ( IMHO ) on Cisco software ( not 100% ) so you should be able to do whatever you need. Regards, Edvin Seferovic
