[Samba] Winbind troubles

[Matthew Daubenspeck]

I've rolled 2 virtual servers running Ubuntu 12.04 LTS and have
installed the SerNet packages. SRV1 has the AD setup and SRV2 is a
member server. I've followed the wiki for both servers to the letter,
and winbind still refuses to grab info on the member server. 

I rolled the provision with --use-rfc2307, added a bunch of users with
samba-tool. I then manually created a group and made sure it had valid
gid. I then did the same with the 3 users, made sure their primary group
was set, and they had valid UIDs. All 3 users have UIDs of 10000, 10001,
and 10002. The single group has a GID of 10000 and all 3 users are a
member.

I joined the domain fine, everything appears correct in DNS, and the
SRV2 member server shows up in ADUC under Computers. Both smb.conf files
match exactly (except for the domain names) the config file
examples in the wiki articles.

wbinfo -u and wbinfo -g both work and pull the proper users/groups.
However, when I run getent passwd all I get is local users.

I checked and re-checked libnss_winbind.so with ldconfig -v, and that is
there as well. What the heck could I be missing? I've followed
everything to the letter.
