[Samba] help with winbind!

[Wilson A. Galafassi Jr.]

hello!
any help me with winbind.
i need to use samba/winbind just only to provide autentication with ntlm
for squid.
programs versions: linux rh 8.0 - squid 2.5S1 - samba 2.2.6

remember: the use of samba/winbind is only to provide autentication for
squid with ntlm.

MY smb.conf
workgroup = CENTROADM
password server = PMF
security = domain
winbind uid = 10000-20000
winbind gid = 10000-20000
winbind use default domain = yes

that configuration of smb.conf is in SQUID FAQ.

ok. when i join in a domain is everything ok. but when i type wbinfo -t
says: could not check secret.

what is incorrect?
any help me

thanks
