[Samba] Can join AD 2003 domain; can't list shares from other servers

I set up an old laptop with Xubuntu 9.10. I configured Samba as to work 
with my Win2003 AD domain that has MS Services for Unix installed.

I can get a Kerberos ticket. I successfully added the laptop to the AD 
domain. wbinfo -a shows me all users, domain and local. wbinfo -g shows 
me all groups. wbinfo -a user%password returns successfully. "getent 
passwd"  works as expected - I see local users, and domain users.

"net ads info" works correctly, returning info.

LDAP server:
LDAP server name: dim-win2300.DaCrib.local
Bind Path: dc=DACRIB,dc=LOCAL
LDAP port: 389
Server time: Fri, 23 Apr 2010 13:12:53 EDT
KDC server:
Server time offset: 1

And yet:

$ smbclient -L workhorse
Enter turgon's password:
session setup failed: NT_STATUS_ACCESS_DENIED

I have no idea why it's failing; I'm not seeing anything in the samba or
winbind logs. (workhorse is Ubuntu 9.10, configured as a domain member 

I can do the reverse; from "workhorse" I can see all the shares on the

Hints as to where to go next? It must be something wrong on this 
specific laptop, since it works from my other server,
but I dunno where, since all the other tests work. Firewall is off, on
both machines.
