  Put the special users in the “users” file.  Then, be sure that they’re not using ntlm_auth:

bob	Cleartext-Password := “hello”, MS-CHAP-Use-NTLM-Auth := no

  The “users” file puts entries into a binary tree.  So it’s fast.  The performance hit (if any) will be negligible compared to the cost of doing SSL.  The RSA calculations need for SSL are *slow*.
