That would be great.

I've been learning a lot in the last few days...

I can't find "dlopen" in any of my share libraries.    In doing further
research, it seems that HP has added "dlopen" only in the 64-bit version of
HP-UX 11, which unfortunately I am not running.

According to
http://www.devresource.hp.com/devresource/Docs/Refs/SunPort/Linkers.html the
corresponding library in HP-UX 11.0 32-bit is "shl_load".

However, I think it probably shouldn't matter, because mod_auth_pam doesn't
call dlopen directly, it just calls the system pam routines through
<security/pam_appl.h>  right?

I still don't quite understand how it all fits together, but I'm trying to
learn :-)

I can't say I understand it all, but it appears that the 64-bit HP-UX 11
does use ELF, but the 32-bit uses their SOM binary format that PA-RISC has
used for the last 10 years.   It sounds like they are trying to
update/improve in 64-bit, but I'm just not there.  Darn.
