[Samba] SID problem with working samba

[toni]

hello,

i have 1 PDC and 1 BDC using smbldap, and now i'm adding a server (as a
domain member, not BDC) that will have shares to be mounted by the
clients.

this server also uses smbldap and, at this moment, the service is
working almost normally.

the problem seems to be the typical SID problem, but my new samba
reports to have the same SID that the PDC and BDC have, and users can
log into the domain and map shares. however, when mapping shares log
file prints these lines:

[2008/01/22 21:06:13, 0, effective(0, 0), real(0, 0)]
passdb/passdb.c:lookup_global_sam_name(596) User nobody with invalid
SID S-1-5-21-3094878921-2476751602-3662942323-501 in passdb
[2008/01/22 21:06:56, 0, effective(0, 0), real(0, 0)]
passdb/passdb.c:lookup_global_sam_name(596) User USER with invalid
SID S-1-5-21-3094878921-2476751602-3662942323-12534 in passdb

also, smbclient -L also gives the same error.

i'm guessing that these error introduces latency, so shares are not
mounted as fast as i would like.

system ldap is working and samba check user credentials correctly
against ldap, with a valid SID also...

where can be the problem? any ideas?

thanks in advance,
