[Samba] Problems with winbind cache

Hi guys!!


I'm facing problem with Samba 4 + winbind that I spent some days to solve
that without success and I'll appreciate any help.


I self compile samba 4 and apparently everything is working fine. I installed
samba on six distributed servers at remote branch offices and all users, groups,
dns and other components are replicating with success.


But last week I saw that windind cache was not been updated and when I try to
get users and groups with getent command, new members is not shown.


I tried some tricks and tips that I found in several websites and forums, but
nothing is working. Yesterday I tried to flush winbind cache with command:


net cache flush


All winbind cache has been erased, but is not updated and now I don't have
any users and groups when I try to get with getent command.


I read in the winbind manual that when I restart the daemon, all cache is erased
and updated, but this not happens. I'm not found where winbind saves its
cache!

[Samba] Problems with winbind cache

Try changing your nsswitch.conf to 

passwd:     files winbind sss
shadow:     files sss
group:      files winbind sss

now do. 

net cache flush

restart winbind 

wbinfo -u
wbinfo -g 
getent passwd username 
getent passwd groupname

First, remove ALL these lines from the DC smb.conf, they either
shouldn't be there, or are default settings:

  passdb backend = samba_dsdb
  idmap config * : backend = tdb
  idmap config *:range = 70001-80000
  idmap config LOVATO:backend = ad
  idmap config LOVATO:schema_mode = rfc2307
  idmap config LOVATO:range = 500-40000
  vfs objects = dfs_samba4, acl_xattr
  winbind use default domain = yes
  winbind nss info = rfc2307
  winbind trusted domains only = no
  winbind cache time = 10
  winbind refresh tickets = yes
  map archive = No
  map readonly = no
  store dos attributes = Yes
  dos filemode = yes

Change /etc/krb5.conf to:

[libdefaults]
        default_realm = LOVATO.INTRANET
        dns_lookup_realm = false
        dns_lookup_kdc = true

Finally, you are NOT using winbind!!

Change /etc/nsswitch to:

passwd:     files winbind
shadow:     files
group:      files winbind

You will then be using winbind.

Just a note, running 'wbinfo -u' or 'wbinfo -g' is pretty
meaningless
on a Unix machine, it just shows the users are in AD, you need to run
'getent passwd USERNAME' and receive an output to know it is working.

[Samba] Problems with winbind cache

Try cleaning up your smb.conf also. 

 
>   vfs objects = dfs_samba4, acl_xattr 
Bit lower.
>   vfs objects = recycle full_audit 
Set this as : vfs objects = dfs_samba4, acl_xattr, recycle full_audit

 

Your using : >   winbind nss info = rfc2307 

So remove these lines 
>   idmap config * : backend = tdb
>   idmap config *:range = 70001-80000
>   idmap config LOVATO:backend = ad
>   idmap config LOVATO:schema_mode = rfc2307
>   idmap config LOVATO:range = 500-40000
 

 

2 x : 
>   disable spoolss = yes
>   disable spoolss = yes
 

Etc, so backup your smb.conf and cleanup first. 

 

As example, this is all i have.

 

[global]

        workgroup = NTDOM

        realm = REALM

        # netbios name is not needed, the computer it hostname wil be use, i
think its handy to have it here.

        netbios name = DC1

 

        server role = active directory domain controller

        # if you run bind_dlz and not samba dns, this is sufficent. 

        server services = -dns

 

        # Dont forget to set the idmap_ldb on ALL DC's if you use it

        idmap_ldb:use rfc2307 = yes

 

        winbind nss info = rfc2307

        winbind expand groups = 4

 

        # with rfc2307 this is only needed on the DC. 

        template shell = /bin/bash

        template homedir = /home/users/%U

 

        # disable printing completely, when set empty no error log messages.

        load printers = no

        printing = bsd

        printcap name = /dev/null

        disable spoolss = yes

 

        # disable usershares creating, when set empty no error log messages.

        usershare path 
 

        # Add and Update TLS Key

        tls enabled = yes

        tls keyfile = /........key.pem

        tls certfile = /........cert.pem

        tls cafile = /....... ca.pem

Try changing your nsswitch.conf to 

passwd:     files winbind sss
shadow:     files sss
group:      files winbind sss

now do. 

net cache flush

restart winbind 

wbinfo -u
wbinfo -g 
getent passwd username 
getent passwd groupname
