Hi all,
"pam_userdb.so" from pam-0.75-48 is linked against threaded libdb-4.0, that
can cause bigger problems. This was the reason to bundle a libdb with pam
(see changelog from pam-0.77-0), but at Red Hat Linux 9 this wasn't done.
So "Very Bad Things" can happen if a unthreaded application uses the
threaded pam_userdb.so...
I reported that as bug (#120558) a week ago, but if I'm realistic, I don't
believe that my issue is fixed before the end of lifetime of Red Hat Linux
9 is reached :-(
So I started my own test to link pam against a unthreaded libdb-4.0, which
always fails with the following error:
--- snipp ---

/bin/sh ./libtool --mode=compile cc -c -I. -I../dist/../include

I did the following (it's more or less a simple hack, that should
theoretically work):
--- snipp ---

Any ideas? I would be very happy, if someone could help me to solve that
problem :-)
With kind regards,
