samba - May 2019 - Group policies are not applied

Hai, 
 
That -k  should use the kerberos auth. 
we should think about a bit better description here. 
 
When your root/Administrator then it works ok also. 
Wel, you found the problem and you where able to fix it, so im happy. 
 
and good to see that you did not have any errors running: samba-tool ntacl
sysvolreset
 
Thanks for the notice back. 
 
Greetz,

The -k option requires an option.  From man page, -k KERBEROS, but 
when I use it I get this.  What is the -K option suppose to do? 

Ub18.04> samba-tool ntacl sysvolreset -k KERBEROS 
Usage: samba-tool ntacl sysvolreset <file> [options] 

samba-tool ntacl sysvolreset: error: invalid -k option value: KERBEROS 

I also ran just this. 
samba-tool ntacl sysvolreset 

Then running 'samba-tool ntacl sysvolcheck' returns without error.

Yes, "authenticated users" is set in security filter.

After doing sysvolreset (without -K) I did 2 other things. One was to change 
passwords on the accounts (this was from a search on the error I saw in 
Windows events).  In the end, all is working correctly.  So I cannot 
confirm the fix. 

Thank you,

Do you mean something like replacing 'KERBEROS' with 'yes' ?

Rowland

Good morning Rowland, 

No, in most other utils of samba "-k"  means use kerberos auth, as in
kinit username(@REALM)

Why in this case its -k KERBEROS 

The manual does not tell where KERBEROS stands for the "Kerberos
REALM" or a path to file?
A bit confusing. 

Greetz, 

Louis

OK, if you run this:

samba-tool user create --help

Under:
  Credentials Options:

You will find this:

    -k KERBEROS, --kerberos=KERBEROS
                        Use Kerberos

What isn't obvious from that, is that 'KERBEROS' is actually
'yes'

rowland at devstation:~$ samba-tool user create user37 P4ssw0rd* -H ldap://dc4
ERROR(ldb): Failed to add user 'user37':  - LDAP error 1
LDAP_OPERATIONS_ERROR -  <00002020: Operation unavailable without
authentication> <>
rowland at devstation:~$ samba-tool user create user37 P4ssw0rd* -H ldap://dc4
-k yes
User 'user37' created successfully

Yes, i know that, seen it and always wondered what is meant buy KERBEROS. 
So uhm, no, this is totaly not obvious. 

Where does it say that KERBEROS == yes?? 
KERBEROS != yes 
KERBEROS ~= REALM (maybe, thats more obvious to me. ) 

Obvious may equal to Assumption, and you know Assumptions.. 
Assumption's are the start of all troubles..  
My previous boss always said that and he was always right, every assumption will
go wrong.

So, if i may suggest, 

     -k yes, --kerberos=yes
            Use Kerberos (ticket) for authentication.

Now it's much better to understand for everyone.
