[Samba] winbind error: rpc_pipe_bind failed

[Manfred Oster]

Hi folks,

I want to set up an samba printserver with cups.
after configuering and starting the deamons I found this entry´s in  my 
winbind logs:

1. log.wb-servername
---------------------
[2006/03/21 18:15:01, 3] 
nsswitch/winbindd_async.c:winbindd_dual_lookupname(695)
  [10919]: lookupname PRINTBAK+root
-----------------------
what does it mean? is this an error, or is this ok?

2. log.wb-BUILTIN

this with google!!!

I´m using SuSE OpenSource 10.0
- samba 3.0.20
- samba-client 3.0.20
- samba-winbind 3.0.20

My smb.conf:

[global]
        workgroup = DOMAIN.COM
        netbios name = PRINTSERVER
        domain master = No
        security = domain
        password server = SERVERPWD
        printing = cups
        printcap name = cups
        printcap cache time = 60
        cups options = raw
        wins proxy = No
        wins server = 192.168.1.xxx
        load printers = Yes
        log level = 1
        winbind separator = +
        idmap uid = 10000-20000
        idmap gid = 10000-20000
        winbind enum users = Yes
        winbind enum groups = Yes

[printers]
        comment = All Printers
        path = /var/tmp
        printable = Yes
        guest ok = No
        browseable = No
        read only = No

[print$]
        comment = Printer Drivers
        path = /var/lib/samba/drivers
        write list = @ntadmin root
        force group = ntadmin
        create mask = 0664
        directory mask = 0775

Especially the error in log.wb-DOMAIN.COM makes me nervous. I want to 
terminate every error, before move this server in productive environment.
After installing a Printer on a XP-Client I get "Access Denied" as 
Status Message. But printing is possible and without errors. How can 
solve this?
If answer, please in reference to the praticular logfile.
I hope someone has any ideas.

Thanks.
Manfred
