Hai Praveen, 


Set these to no.

Its only slowing down your server. 
Use :getent passwd username and you see the users info


> Also, how do we setup a common login script for all users. 
For sysvol/netlogon, It is important todo this in this order! 

First, set this in both shares. 
        acl_xattr:ignore system acls = yes
Restart samba-ad 
.. Why add : acl_xattr:ignore system acls because better ACL rights, less windows problems with GPO's. 
And these are shared only used by windows, so why not. 


Now, set your sysvol SHARE permissions as followed and do this from within windows. 

EVERYONE: READ
Authenticated Users: FULL CONTROL
(BUILTIN or NTDOM)\Administrators: FULL CONTROL
(BUILTIN or NTDOM)\SYSTEM, FULL CONTROL
User/Group system is added compaired to a win2008R2 sysvol, you need this for some GPO settings.

Set your sysvol FOLDER permissions as followed.
Authenticated Users: Read & Exec, Show folder content, Read
(BUILTIN or NTDOM)\Administrators: FULL CONTROL
(BUILTIN or NTDOM)\SYSTEM, FULL CONTROL

Then run this script. 
https://raw.githubusercontent.com/thctlo/samba4/master/samba-check-set-sysvol.sh 
By default it does not change anything, it creates a file you can use to set the rights for sysvol. 
setfacl -R -b --modify-file default-rights-sysvol.acl /var/lib/samba/sysvol/

Now re-check the rights again from a windows pc, if nothing has change then its ok.
If it did, re-apply the right on share/folder again. 

Test a computer, clear its eventlog, reboot and check, clear its eventlog again and reboot again. 
Check again. 


And yes, correct is you run in manualy its fine, thats because then YOU run it, not the computer..
Your Kix script, make sure you are using FQDN names and not only \\servername\..  
But why Kix, yes, can be usefull, i know Kix... but you can do almost anything with Group Policies also. 

And read these, that should give you and idea what todo next.

Well, good luck.
