[Samba] net usersidlist failed?

[Marshall Herington]

I'm not sure if this relates to an earlier problem I wrote in about,
but currently I'm working on this new problem:  Running net
usersidlist reports:

[root at orion samba]# net usersidlist
[2005/07/15 11:37:05, 0] utils/net_rpc.c:net_usersidlist(3853)
  Could not get the user/sid list

Running net rpc user does, however, return a list of valid users. 
I've run samba at debug=10, but can't make heads or tails of the
volumes of stuff that it generates (I'd be happy to post that here if
needed).  Any help would be appreciated.
