Hi, I seem to have radiusd working fine with PAM now, however I have a
strange core dump problem. Users can authenticate successfully, BUT when a
user puts in an incorrect password, radiusd core dumps.
pam_pass: function pam_authenticate FAILED for <fred>. Reason:
Authentication failed
Segmentation Fault(coredump)
The PAM module I am using is the MIT pam_krb5 one, which otherwise works
fine for other PAM enabled applications.
Any ideas on this, anyone seen this behaviour before ?
