After running AuthBy PAM for an certain amount of time...I get
core dumps. I don't see the correlation but I thought I might add
that. I haven't looked for leaks but there is something wrong
with the way Radiator or Authen-PAM uses PAM...I use this same pam
module for several other services that get used hundreds or
thousands of times a day without problems. But with Radiator or
Authen-PAM I get core dumps often.
This is on FreeBSD 4.5-RELEASE (which gets it's pam stuff directly
from the Linux work).
I tried it on other systems as well. Don't know if it is related
(probably not), but maybe there is a problem with Authen-PAM.
