[Samba] net share command

[Lapin(c)]

Hi team,

I need to execute some net share command on a Samba 3.0.4/LDAP server.
I guess this command needs to be run as root, so I use Administrator account
(uid=0,primarygroupsid=512) but I have the following behaviour :
# net share add test=/var/tmp -U administrator%password
- with loglevel 0 : no warning, but no new share
- with loglevel 3 :
[Mon Dec  6 15:39:12 2004
, 1] utils/net_rpc.c:run_rpc_command(141)
  rpc command function failed! (NT_STATUS_UNSUCCESSFUL)

- with loglevel 10 :
[Mon Dec  6 15:39:12 2004
, 5] rpc_parse/parse_prs.c:prs_werror(694)
      001c status: WERR_ACCESS_DENIED
[Mon Dec  6 15:39:12 2004
and server side
[Mon Dec  6 15:39:38 2004
, 5] rpc_parse/parse_prs.c:prs_werror(694)
      0004 status: WERR_ACCESS_DENIED
[Mon Dec  6 15:39:38 2004
, 5] rpc_server/srv_pipe.c:api_rpcTNP(1575)
  api_rpcTNP: called srvsvc successfully
[Mon Dec  6 15:39:38 2004

Did I miss something ?

Many thanks
