1133            client 1st tries an OpenPrinterEx with access==0, MUST be allowed.
1134
1135            Then both Win2k and WinNT clients try an OpenPrinterEx with
1136            SERVER_ALL_ACCESS, which we allow only if the user is root (uid=0)
1137            or if the user is listed in the smb.conf printer admin parameter.

1139            Then they try OpenPrinterEx with SERVER_READ which we allow. This lets the
