Hi Bjørn,
From what you mention here it sounds like you have four
sambaDomainName=UNIX entries (objectClass: sambaDomain) with different
sambaSID attributes. Effectively 4 different domains, on 4 different
servers all with the same name.
Users have a sambaSID entry in their LDAP record, and the first portion
of this needs to be the same as the sambaSID for the *domain* they are
logging on to. If it's not then it wont work.
In answer to your point at the end, yes you can do this and it is what
you are "supposed" to do, as far as I know.
If you do "net getlocalsid" on each of your SLES machines, the SID that
is returned should be the same for all of them if you want them all to
be controllers on your domain. If it's not, pick the SID you want - i.e.
the sambaSID all your users have in their LDAP records - then "net
setlocalsid MYDOMAINSID" on the servers you wish to change to that SID.
(NB: On a domain, "net getlocalsid" and "net getlocalsid MYDOMAIN"
should return the same.)
Then go into your LDAP directory and delete all but one of the
sambaDomainName=UNIX entries, and ensure the remaining one has sambaSID
set to MYDOMAINSID.
That is probably all you need to do.
HTH,
Phil
