No reactions? What's wrong? Did i do anything wrong? Is this "bug" to harmless? Is pam_access deprecated?

I'm not sure if this is your problem, but one thing that can cause this is if a PAM module does not correctly handle the appdata_ptr.


If the module doesn't pass it back (eg passes a null) then sshd ( <= 3.8.1p1, I think) will segfault when it attempts to deref it. From 3.9p1, sshd will check for null and give a warning instead of crashing.

Wouldn't the problem you describe be a more general one?
There was only one specific account, for which the problem occured. There might have been more, but i didn't find any :-(


Well, the problem has now disappeared. I cannot reproduce it anymore :-(
