[Samba] LDAP unable to add Idmap

[Adi Nugraha]

Hi,

I'm trying to setup a Samba with ldap backend, I followed tha samba by
example chapter 6, followed the instcution in the book, and when it says to
add an idmap data container, LDAP won't allow me to add the idmap something
like this :

adding new entry "ou=Idmap,dc=test,dc=co,dc=id"
ldapadd: update failed: ou=Idmap,dc=test,dc=co,dc=id
ldap_add: Constraint violation (19)
        additional info: structuralObjectClass: no user modification allowed

and
getent passwd | grep Domain returned :

[root at localhost sbin]# getent passwd | grep Domain
Administrator:x:0:512:Netbios Domain Administrator:/home/:/bin/false

at first I thought it was ok, to ignore it as the rest of the validation
according to the book went fine, but when I tried net rpc join -U
Administrator%secret it says that the username or password is incorrect, I
can avoid this by adding a new user with 0 UID and then I can join the
domain, but I can't login after I joined the domain, "Domain is not
available" or something, can anyone help me with this, I even tried
reinstalling everything from scratch ( format the hardrive) this is the 3rd
time already, and I don't know what else I'm missing, Please help me


thx

Adi
