[Samba] Samba on AIX with security = ads - does it actually work?

That may or may not be a red herring.  id_32 and id_64 are not native AIX utilities, but are provided by coreutils.  On my system, the native AIX id command returns data for AD users when winbind is configured.  Interestingly, id_32 returns data also, but more of it.  id_64 indeed says "no such user".  But again, the AIX id command does so I would think it'd be good to go.

You are right though that Samba is built as 32-bit on AIX:

# dump -ov /opt/freeware/lib/WINBIND.so

/opt/freeware/lib/WINBIND.so:

That being the case, I would think we'd want to have a WINBIND.so in /opt/freeware/lib64 as well. Any way to force a 64-bit (or both simultaneously) build?  In this case it was IBM who did the compile.

But regardless, I'm not sure if it matters for the specific error in question...

Thanks again!
