It's been a few weeks since the survey was started. Thanks to everyone who entered their data. The results are still coming in at about 25 per day, so I expect that these numbers will change over time. So far, we have a bit over 500 responses, which makes the data very useful.
I won't get into a detailed explanation of the results, but I will hilight the numbers. I'll see if I can put some graphs on freeradius.org in a few days, too. We have the most interesting result first: ==> Total number of users who are authenticated via FreeRADIUS: 100,000,000 That's impressive. The top 30 sites alone have over 75 million users who are using RADIUS for authentication. With those numbers, it looks like 10% or more of people on the net are authenticated via FreeRADIUS. If we assume that a number of large sites haven't entered their data on the survey, then the percentage is probably much higher, like 25%. FreeRADIUS looks like it's the server of choice for the Internet. Maybe we'll make that the new slogan... ==> Total number of RADIUS servers Many sites (70%) only have 1-2, with 95% of sites having 10 or fewer servers. About 1% has 50-100 servers, though, which is impressive. ==> Databases MySQL is the clear winner at 30%. Next comes the "users" file at 10%, OpenLDAP at 17%, and Active Directory at 14%. ==> Password hashes 40% of passwords are stored as cleartext, 25% as Crypt, 20% as MD5, and 13% as NT hash. ==> Authentication Protocols PAP and CHAP are paired at about 20%. But PEAP, EAP-TLS, and TTLS are each about 10%, too. ==> Configuration updates 75% of sites change their configuration monthly to never. That statistic goes a long way to explaining why so few people need official support. :) ==> Other RADIUS servers ACS and IAS are tied at about 25% each. Cistron and OpenRADIUS are at about 10%, and Funk & Radiator are just under 10%. It looks like FreeRADIUS isn't in the top 5 of RADIUS servers, it's in the top 3, and maybe is even number one! And a large number of people have *never* used a server other than FreeRADIUS. I'm glad to see it's well received. ==> Why FreeRADIUS? Open source, cost, and feature set all came in at about 20% each. ==> What do you need most from FreeRADIUS? Something called "documentation" beat out the next nearest response by nearly 2:1. We'll see if we can work on that. Anyways, thanks for all of the response. We'll use the information to target development for future releases. Alan DeKok. - List info/subscribe/unsubscribe?
