#crontab -e 0 7 * * * ntpdate ad2008domain
5.configure your kerberos, edit which is domain to yourself.
cat /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 = DOMAIN.COM
DNS_lookup_realm = false
dns_lookup_kdc = false
ticket_lifetime = 24h
forwardable = yes
[realms]
DOMAIN.COM = {
kdc = ad1.domain.com
kdc = ad2.domain.com
admin_server = ad1.domain.com
default_domain = DOMAIN.COM
}
[domain_realm]
.domain.com = DOMAIN.COM
domain.com = DOMAIN.COM
[kdc]
profile = /var/kerberos/krb5kdc/kdc.conf
[appdefaults]
pam = {
debug = false
ticket_lifetime = 36000
renew_lifetime = 36000
forwardable = true
krb4_convert = false
}Verify your configuration
#kinit domainadmin@DOMAIN.COM
6. Configure nsswitch.conf like this. The key location is passwd shadow group
/etc/nsswitch.conf passwd: files winbind shadow: files winbind group: files winbind #hosts: db files nisplus nis dns hosts: files dns wins # Example - obey only what nisplus tells us... #services: nisplus [NOTFOUND=return] files #networks: nisplus [NOTFOUND=return] files #protocols: nisplus [NOTFOUND=return] files #rpc: nisplus [NOTFOUND=return] files #ethers: nisplus [NOTFOUND=return] files #netmasks: nisplus [NOTFOUND=return] files bootparams: nisplus [NOTFOUND=return] files ethers: db files netmasks: files networks: files dns protocols: db files rpc: files services: files netgroup: files publickey: nisplus automount: files aliases: files nisplus
7.Configrure PAM like this
cat /etc/pam.d/system-auth #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required /lib/security/$ISA/pam_env.so auth sufficient /lib/security/$ISA/pam_unix.so likeauth nullok auth sufficient /lib/security/$ISA/pam_winbind.so use_first_pass auth required /lib/security/$ISA/pam_deny.so account required /lib/security/$ISA/pam_unix.so account sufficient /lib/security/$ISA/pam_succeed_if.so uid < 100 quiet account sufficient /lib/security/$ISA/pam_winbind.so use_first_pass account required /lib/security/$ISA/pam_permit.so password requisite /lib/security/$ISA/pam_cracklib.so retry=3 type= password sufficient /lib/security/$ISA/pam_unix.so nullok use_authtok md5 shadow password sufficient /lib/security/$ISA/pam_winbind.so use_first_pass password required /lib/security/$ISA/pam_deny.so session required /lib/security/$ISA/pam_limits.so session required /lib/security/$ISA/pam_unix.so session required /lib/security/$ISA/pam_winbind.so use_first_pass session required /lib/security/pam_mkhomedir.so

#testparm
If there is no error, Please continue
10.Add domain
#net ads join -U domainadmin
verify method
#net ads info
#wbinfo -u
#getent passwd
11.Chang your Share folder permission, It's so important
chown userone:userone share folder
12.restart winbind samba
service smb restart
service winbind restart
13.Debug
We can't successful in the first time, So if happen any error, You can check it from /var/log/samba/*
