[Samba] Unable to add a printer driver

[John Davis]

We are using Samba 2.2.0 on Redhat 7.2. Adding printer drivers produces
an error:

-- begin --
[root at localhost /root]# rpcclient localhost -U root%<redacted> -c
"setdriver portlnd6 \"HP LaserJet 4 Plus\""
INFO: Debug class all level = 3   (pid 2032 from pid 2032)
session setup ok
Domain=[SIERRAOREGON] OS=[Unix] Server=[Samba 2.2.0]
result was NT code 00000709
-- end --

The log entry for thgis command looks like this:
[2003/12/04 00:33:46, 3] smbd/connection.c:yield_connection(54)
  Yielding connection to IPC$
[2003/12/04 00:33:46, 2] smbd/connection.c:utmp_yield(785)

  Server exit (normal exit)

Tring the same thing with the printer admin account produces no output
of any kind. IS this a known problem, and if so, would it be fixed by
upgrading to the new Samba 3.0?
