Problems building 'nsswitch' on HP-UX 11.0 (possible configure issue)

[Ladner, Eric (Eric.Ladner)]

I'm trying to move to full domain membership on a couple of servers and
I'm rebuilding 3.0 on HP-UX 11.0 with GCC using --with-pam and
--with-winbind

I'm having a heck of a time trying to build the pam shared libraries.
Doing a configure seems to find everything ok, except it thinks the pam
modules aren't usable for some reason (see Example 1 below).  Also,
'make everything' doesn't hit the nsswitch directory, I had to 'make
nsswitch' to get it to build.

When I force a 'make nsswitch' I get a ton of errors from
winbind_nss_solaris.c (see Example 2 and Example 3 below).  It looks
like it's just missing the definition of nss_backend_t, so I poked
through some headers and found the definition in winbind_nss_hpux.h and
tried to figure out why that wasn't getting included.

Turns out that in nsswitch/winbind_nss.h, the HPUX conditional wasn't
getting hit because the HAVE_NSSWITCH_H flag wasn't set (both had to be
true).  I checked the config.log and it didn't even check for it, and I
do have it on the system (/usr/include/nsswitch.h).  Temporarily, I
removed the extra condition behind HPUX in winbind_nss.h and it compiled
ok.

Cheers,

Eric
