Hi Adam.
Thanks for your reply. But I've not added the Computers account for
paris$ manually. Samba give me the error, but it also make the entry in
ldap.
The entry:
# paris$, Computers, DOMINIO
dn: uid=paris$,ou=Computers,dc=DOMINIO
objectClass: top
objectClass: account
objectClass: posixAccount
objectClass: sambaSamAccount
cn: paris$
uid: paris$
uidNumber: 2008
gidNumber: 515
homeDirectory: /dev/null
loginShell: /bin/false
description: Computer
gecos: Computer
sambaSID: S-1-5-21-1849485170-1217343015-651458238-1008
displayName: Computer
sambaAcctFlags: [W ]
is created by samba with the add machine script =
/usr/sbin/smbldap-useradd -w "%u"
Now I've deleted paris$ machine account, when I add the client to the
domain, on the client give always Domain DOMINIO Joined, but samba logs
give me:
[2009/05/01 10:55:05, 0] rpc_server/srv_netlog_nt.c:get_md4pw(306)
get_md4pw: Workstation PARIS$: no account in domain
[2009/05/01 10:55:05, 0]
rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(502)
_netr_ServerAuthenticate2: failed to get machine password for account
PARIS$: NT_STATUS_ACCESS_DENIED
and samba has added this entry, that differs from the previous:
# paris$, Computers, DOMINIO
dn: uid=paris$,ou=Computers,dc=DOMINIO
uid: paris$
sambaSID: S-1-5-21-1849485170-1217343015-651458238-1010
displayName: Computer
objectClass: sambaSamAccount
objectClass: account
sambaAcctFlags: [W ]
(PS. sometimes it give me an account such this, other, it give me a
complete account, or it says me "Creation of workstation account
Failed"...and I'don't know if it's a bug or problem configuration...this
only with Linux Client...(Slackware 12.1))
Then, after a valid account creation by samba, and join with the client,
in the linux client I cannot login with a user on LDAP, and when try to
rejoin the domain it still give me:
[2009/05/01 10:56:54, 0]
rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(520)
_netr_ServerAuthenticate2: netlogon_creds_server_check failed.
Rejecting auth request from client PARIS machine account PARIS$
Now, i've tried another thing, I've removed paris$ entry, and added
manualli with smbldap-useradd -w paris,, the entry in ldap is:
# paris$, Computers, DOMINIO
dn: uid=paris$,ou=Computers,dc=DOMINIO
objectClass: top
objectClass: account
objectClass: posixAccount
cn: paris$
uid: paris$
uidNumber: 2014
gidNumber: 515
homeDirectory: /dev/null
loginShell: /bin/false

gecos: Computer
after joining, samba log give:
[2009/05/01 11:26:35, 0] rpc_server/srv_netlog_nt.c:get_md4pw(306)
get_md4pw: Workstation PARIS$: no account in domain
[2009/05/01 11:26:35, 0]
rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(502)
_netr_ServerAuthenticate2: failed to get machine password for account
PARIS$: NT_STATUS_ACCESS_DENIED
but the entry become:
# paris$, Computers, DOMINIO
dn: uid=paris$,ou=Computers,dc=DOMINIO
objectClass: top
objectClass: account
objectClass: posixAccount
objectClass: sambaSamAccount
cn: paris$
uid: paris$
uidNumber: 2014
gidNumber: 515
homeDirectory: /dev/null
loginShell: /bin/false

sambaSID: S-1-5-21-1849485170-1217343015-651458238-1016

sambaAcctFlags: [W ]
with another rejoin logs give:
[2009/05/01 11:28:03, 0]
rpc_server/srv_netlog_nt.c:_netr_ServerAuthenticate2(520)
_netr_ServerAuthenticate2: netlogon_creds_server_check failed.
Rejecting auth request from client PARIS machine account PARIS$
This behaviour is the same if I put in config file "add machine script =
/usr/sbin/smbldap-useradd -w "%m" versus add machine script =
/usr/sbin/smbldap-useradd -w "%u"
Possible that's a problem that concern slackware Client? SmbVersion of
Client is 3.0.28a.
Thanks in advance.
