    ##############################################################################

    # Notes: to use to dual ldap servers backend for Samba, you must patch
    # Samba with the dual-head patch from IDEALX. If not using this patch
    # just use the same server for slaveLDAP and masterLDAP.
    # Those two servers declarations can also be used when you have
    # . one master LDAP server where all writing operations must be done
    # . one slave LDAP server where all reading operations must be done
    #   (typically a replication directory)

    # Slave LDAP server
    # Ex: slaveLDAP=127.0.0.1
    # If not defined, parameter is set to "127.0.0.1"
    slaveLDAP="127.0.0.1"

    # Slave LDAP port
    # If not defined, parameter is set to "389"

    # Ex: masterLDAP=127.0.0.1
    # If not defined, parameter is set to "127.0.0.1"
    masterLDAP="127.0.0.1"

    # Master LDAP port
    # If not defined, parameter is set to "389"
    masterPort="389"

    # Use TLS for LDAP

    # (you should also used the port 389)

### 8.2 Changing the administrative account (`ldap admin dn` in `smb.conf` file)

If you don't want to use the `cn=Manager,dc=idealx,dc=com` account anymore, you can create a dedicated account for Samba and the smbldap-tools scripts. To do this, create an account named samba as follows (see section 4.2.1 for a more detailed syntax) :

    smbldap-useradd -s /bin/false -d /dev/null -P samba

This command will ask you to set a password for this account. Let's set it to samba for this example. You then need to modify configuration files:

- file `/etc/opt/IDEALX/smbldap-tools/smbldap_bind.conf`

          slaveDN="uid=samba,ou=Users,dc=idealx,dc=com"
          slavePw="samba"
          masterDN="uid=samba,ou=Users,dc=idealx,dc=com"
          masterPw="samba"

- file `/etc/samba/smb.conf`

          ldap admin dn = uid=samba,ou=Users,dc=idealx,dc=com

  don't forget to also set the samba account password in `secrets.tdb` file :

      smbpasswd -w samba

- file `/etc/openldap/slapd.conf`: give to the samba user permissions to modify some attributes: this user needs to be able to modify all the samba attributes and some others (uidNumber, gidNumber ...) :

      # users can authenticate and change their password
      access to attrs=userPassword,sambaNTPassword,sambaLMPassword,sambaPwdLastSet,sambaPwdMustChange
            by dn="uid=samba,ou=Users,dc=idealx,dc=com" write
            by self write
            by anonymous auth
            by * none
      # some attributes need to be readable anonymously so that 'id user' can answer correctly
      access to attrs=objectClass,entry,gecos,homeDirectory,uid,uidNumber,gidNumber,cn,memberUid
            by dn="uid=samba,ou=Users,dc=idealx,dc=com" write
            by * read
      # somme attributes can be writable by users themselves
      access to attrs=description,telephoneNumber
            by dn="uid=samba,ou=Users,dc=idealx,dc=com" write
            by self write
            by * read

      access to attrs=cn,sambaLMPassword,sambaNTPassword,sambaPwdLastSet,sambaLogonTime,sambaLogoffTime,sambaKickoffTime,sambaPwdCanChange,sambaPwdMustChange,sambaAcctFlags,displayName,sambaHomePath,sambaHomeDrive,sambaLogonScript,sambaProfilePath,description,sambaUserWorkstations,sambaPrimaryGroupSID,sambaDomainName,sambaSID,sambaGroupType,sambaNextRid,sambaNextGroupRid,sambaNextUserRid,sambaAlgorithmicRidBase

            by self read

      access to dn.base="dc=idealx,dc=com"

### 8.3 known bugs

- Option -B (user must change password) of `smbldap-useradd` does not have effect: when `smbldap-passwd` script is called, sambaPwdMustChange attribute is rewrite.
