Comment #1 on issue 609 by ste...@konink.de: Cherokee crashes upon PAM
authentication
http://code.google.com/p/cherokee/issues/detail?id=609

My hunch on this is that PAM doesn't allow reuse of the Handle. And there
is race.

Are you using some uncommon pam module? I would have guessed a segfault in
a pam
module rather. But that's maybe because I have just been messing with a
very unstable
one.

Please provide your /etc/pam.d/cherokee file and if possible reproduce with
pam
debugging symbols.

Comment #4 on issue 609 by bram.swenson: Cherokee crashes upon PAM
authentication
http://code.google.com/p/cherokee/issues/detail?id=609

seeing the same issue here in ubuntu karmic. one thing possibly odd about
karmics pam
config is that it requires sha512 per this line in
/etc/pam.d/common-password

password [success=1 default=ignore] pam_unix.so obscure sha512

i would be happy to gather any other info needed to get this issue resolved.

Comment #5 on issue 609 by skarcha: Cherokee crashes upon PAM authentication
http://code.google.com/p/cherokee/issues/detail?id=609

Reproduced.

From PAM manpage:

==============
The libpam interfaces are only thread-safe if each thread within the
multithreaded
application uses its own PAM handle.
==============

Applying the (simple again) attached patch, works without problems, but I'm
not sure
whether it's the best solution. Please, review.
