Tag Line : /etc/smb.conf,forward.zone,reverse.zone,configure samba PDC with primary DNS using BIND in rhel 6, centos 6,linux.

Step 1: Installing Samba
Step 2: Preparing the Configuration Files
Step 3: Starting the Service
Step 4: User Management
Step 5: Now that the Unix users are created, time to create the samba users.
Step 6: Add the client entry
Step 7: Make a DNS entry of mypc1 in forward.zone and reverse.zone in /var/named/ as below
@Here change in /etc/smb.conf file

Step 1: Installing Samba

[root@server1 ~]#yum install samba

Step 2: Preparing the Configuration Files

[root@server1 ~]#cd /etc/samba/
[root@server1 samba]# cp smb.conf smb.conf.bak

@ Edit the main smb.conf files

[root@server1 samba]# vim smb.conf
workgroup = howtoc
## Here are the modifications
## The actual name of the domain ##
 hosts allow = 127. 192.168.10.
## The IP range to be allowed. Alternatively, the “interfaces” parameter may be used. ##

security = user
passdb backend = tdbsam
domain master = yes
domain logons = yes
logon path =
## Because netlogons create more problems than benefit, we have used an empty logon path to force user accounts to be created at client end machines. ##
## save & exit ##

Step 3: Starting the Service

[root@server1 ~]#service smb restart; chkconfig smb on
[root@server1 ~]#service nmb restart; chkconfig nmb on
[root@server1 ~]#netstat -tulpn | grep mb

Step 4: User Management

@ To add clients into the domain, both machine and human users must be created. There are a couple of steps, but it's not hard.
[root@server1 ~]#mkdir –m 1777 /home/profiles
[root@server1 ~]#mkdir –m 1777 /home/netlogon
[root@server1 ~]#groupadd  -g 501 computers
[root@server1 ~]#groupadd employee
[root@server1 ~]#useradd -d /dev/null –g 501 computers  -s /sbin/noLogin computerName$

##### please note that machine users always end with $ #####

Step 5: Now that the Unix users are created, time to create the samba users.

[root@server1 ~]#useradd -g employee user1

[root@server1 ~]#smbpasswd -a root
### The administrative user is created. It is recommended that the password is different
### from the actual UNIX password. ####

[root@server1 ~]#smbpasswd -a -m computerName 
[root@server1 ~]#smbpasswd -a user1

Step 6 : Add the client entry
Note :: if I wanto to join computer “ mypc1” to “howtoc “ domain then,

[root@server1 ~]#useradd -d /dev/null –g 501 computers  -s /sbin/noLogin mypc1$
[root@server1 ~]#smbpasswd -a -m mypc1

Step 7 :Make a DNS entry of mypc1 in forward.zone and reverse.zone in /var/named/ as below
@forward.zone

[root@server1 ~]#vim /var/named/forward.zone
$TTL 1D
@ IN SOA server1.howtoc.com. root.server1.howtoc.com. (
     0 ; serial
     1D ; refresh
     1H ; retry
     1W ; expire
     3H ) ; minimum
                IN    NS server1.howtoc.com.
    IN     A   192.168.10.2
server1   IN      A 192.168.10.2
mypc1   IN    A 192.168.10.3

@reverse.zone

[root@server1 ~]#vim /var/named/reverse.zone
$TTL 1D
@ IN SOA server1.howtoc.com. root.server1.howtoc.com. (
     0 ; serial
     1D ; refresh
     1H ; retry
     1W ; expire
     3H ) ; minimum
 IN NS server1.howtoc.com.
 IN PTR howtoc.com.
 IN A 255.255.255.0
2 IN PTR server1.howtoc.com.
3 IN PTR mypc1.howtoc.com

Here change in /etc/smb.conf file

[root@server1 ~]#vim /etc/smb.conf
