[Samba] 3.0.21c: idmap_rid segfaults on AIX 5.3 ML4

[Jurjen Oskam]

Hi everyone,

I'm trying to use idmap_rid on an AIX 5.3 ML4 machine. Samba compiled
successfully using the IBM compiler (vac.C) version 6. The only
programs I supplied where db and libiconv.

I followed the instructions, and put nsswitch/WINBIND in /usr/lib/security,
and edited /usr/lib/security/methods.cfg.

When I start "winbindd -i", it coredumps with a Signal 11:
