i'm getting a correct behaviour with a passdb backend ldapsam, but also
a 40-60 seconds timeout when connecting to shares and the following
lines in the log file:

[2008/01/23 18:43:27, 0, effective(0, 0), real(0, 0)]
  User USER with invalid SID
S-1-5-21-3094878921-2476751602-3662942323-12534 in passdb

i've read the documentation, chapter 7 as you suggested, and i've
removed the ldap* configuration options and added the option
"winbind trusted domains only = yes"

with this new configuration, the 'invalid SID' lines are not shown but
i'm getting the annoying timeout when connecting to shares. also, now,
"pdbedit -L USER" can't find users and "smbclient -L -U USER%passwd" do
a timeout after 20 seconds (this is the same as before)

now, my smb.conf contains:

    netbios name = SERVERNAME
    workgroup = DOMAIN
    security = domain
    local master = no
    password server = *
    winbind trusted domains only = yes
    mangling method = hash2
    encrypt passwords = yes
    ; wins is the PDC
    wins server =

this server has also a ldap server to resolve system users (via
nsswitch), and the contents are replicated from a master ldap in the
PDC (i think this is what you are proposing, isn't it?)

thanks for your help
