oo.  then can you do a cvs update, _then_ do a diff?

urr, the problem is that the \PIPE\NETLOGON conncetion is done

therefore ,  the standard_subxxx() substitutions will substitute
anonymous-user for %U etc.

i described this in great detail on samba tech, last month.  see archives
for details.

nope.  1) there isn't any "authentication", not in the SMB-sense of the
word.  _this_ is the authentication that SMB-session-authentication

2) the NETLOGON API is unicode (because NT is unicode).  therefore it's
not OK to convert to ascii, perform substs, then convert to unicode,
