The one entered by the user is in User-Password (or CHAP-Password or
whatever), not Cleartext-Password.

The password that auth_pap/auth_chap compares against is in a
Cleartext-Password attribute in the control list. So we'd need multiple
instances of that.

No, we're using mysql, but it doesn't make any difference to this

That doesn't work - try it and see:

somebody	Cleartext-Password := "foo"
		Fall-Through = Yes

somebody	Cleartext-Password += "bar"

The auth_pap / auth_chap modules only validate the first Cleartext-Password
