AD Intergration with Cent OS 6
Hello,

I am integration AD authentication to Cent OS 6 servers. I am running to this error when I tried to join with AD server.

error message :

Code:
# net ads join -U 504783
Host is not configured as a member server.
Invalid configuration.  Exiting....
Failed to join domain: This operation is only allowed for the PDC of the doma        in.
#

configuration file of samba smb.conf under [global] is updated with this info.

Code:
workgroup = ctab
realm = CTAB.ALPHA.COM
security = ads
idmap uid = 7000-500000
idmap gid = 7000-500000
template shell = /bin/bash
template homedir = /home/%U
winbind use default domain = true
winbind offline logon = false
winbind nss info = rfc2307
idmap config TRD:backend = ad
idmap config TRD:defauly = yes
idmap config TRD:range = 70000-500000
idmap config TRD:schema_mode = rfc2307
server string = Samba Server Version %y

I have updated krb5.conf as this

Code:
#more /etc/krb5.conf
[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = CTAB.ALPHA.COM
 dns_lookup_realm = false
 dns_lookup_kdc = false
 ticket_lifetime = 24h
 renew_lifetime = 7d
 forwardable = true

[realms]
 CTLAB.ALPHA.COM = {
  kdc = ctab.alpha.com
  admin_server = ctab.alpha.com
 }

[domain_realm]
 .ctab.alpha.com = CTLAB.ALPHA.COM
 ctab.alpha.com = CTLAB.ALPHA.COM
#

idmap_tdb

IDMAP_TDB(8)															      IDMAP_TDB(8)

NAME

       idmap_tdb - Samba's idmap_tdb Backend for Winbind

DESCRIPTION

       The  idmap_tdb  plugin  is  the default backend used by winbindd for storing SID/uid/gid mapping tables and implements both the "idmap" and
       "idmap alloc" APIs.

IDMAP OPTIONS

       range = low - high
	  Defines the available matching uid and gid range for which the backend is authoritative. Note that the range commonly matches the  allo-
	  cation range due to the fact that the same backend will store and retrieve SID/uid/gid mapping entries. If the parameter is absent, Win-
	  bind fail over to use the "idmap uid" and "idmap gid" options from smb.conf.

IDMAP ALLOC OPTIONS

       range = low - high
	  Defines the available matching uid and gid range from which winbindd can allocate for users and groups. If the parameter is absent, Win-
	  bind fail over to use the "idmap uid" and "idmap gid" options from smb.conf.

EXAMPLES

       The following example is equivalent to the pre-3.0.25 default idmap configuration using the "idmap backend = tdb" setting.

	    [global]
		idmap domains = ALLDOMAINS
		idmap config ALLDOMAINS:default = yes
		idmap config ALLDOMAINS:backend = tdb
		idmap config ALLDOMAINS:range	= 10000 - 50000

		idmap alloc backend = tdb
		idmap alloc config:range = 10000 - 50000

AUTHOR

       The  original  Samba  software  and  related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.
