  For one, be sure that the password in SQL is Cleartext-Password, and not User-Password.

  Then, decide which users need to be authenticated based only on User-Name.

  Then, configure that.  The PAP module is listed in the "authorize" section, and sets 'Auth-Type = PAP', but ONLY if Auth-Type is not already set.

  You can force authentication success by setting 'Auth-Type = Accept'.

  So the solution is simple:

authorize {

	if (User-Name == "testing") {     # as an example
		update control {
			Auth-Type := Accept

	# this should be the last thing in the "authorize" section.
