What happens with :

$ getent passwd
$ wbinfo -u

How was your winbind conpiled? I think I found this to be an issue when
compiling with the winbind ldap hack (ie running ./configure for samba
with '--with-winbind-ldap-hack'). Try compiling without this option (if
you don't need it).

If this is not the case, you may also have success with nscd (typically
used for NIS and LDAP to cache lookups), but winbind is supposed to do
caching anyway, and I normally don't find it necessary.
