This is really just a post for me to keep track of sites that have got or had performance issues with FreeRADIUS when authenticating to Active Directory via ntlm_auth and Samba.

The issue crops up on the FreeRADIUS mailing list with an increasing frequency, so trying to collate posts to keep track of what people have tried as a solution.

Note the vast majority of sites are universities. I believe this is because there is a unique problem that does not occur in business: once an hour, many students and staff all walk around the site at the same time, authenticating to different wireless access points. This causes massive increase in concurrent authentications.
