[Samba] After Update to 4.2, Samba is unusuable as member server / No user and goup resolution

Hello everybody,

I've bin running Samba as a AD member server for ages (Debian stable). 
After the last update to 4.2, I just can't get it to work.

Symptoms: unable to map AD user / groups.

After two days of successlessly fiddling (and moving all data to another 
server with still Samba 3.6, which I will definitely NOT update at the 
moment), I decided to purge my Installation and start over again like 
described in 
<https://wiki.samba.org/index.php/Setup_Samba_as_an_AD_Domain_Member>

So now my setup is (all names and IPs are masked, but are correct here):

********************************************************************
smb.conf
********************************************************************
[global]

netbios name = test-fileserver3
security = ADS
workgroup = AD
realm = AD.test.loc

log file = /var/log/samba/%m.log
log level = 3

dedicated keytab file = /etc/krb5.keytab
kerberos method = secrets and keytab
winbind refresh tickets = yes

winbind trusted domains only = no
winbind use default domain = yes
winbind enum users  = yes
winbind enum groups = yes

idmap config *:backend = tdb
idmap config *:range = 2000-9999

idmap config AD:backend = ad
idmap config AD:schema_mode = rfc2307
idmap config AD:range = 10000-95000

winbind nss info = template
#       template shell = /sbin/nologin
#       template homedir = /home/%U
********************************************************************



********************************************************************
nsswitch.conf
********************************************************************
passwd: files winbind
group:  files winbind
hosts:  files dns.
shadow: files winbind

networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup: nis
********************************************************************



My krb5.keytab has been generated correctly. I also have a krb5.conf:

********************************************************************
krb5.conf
********************************************************************

[libdefaults]
default_realm = AD.TEST.LOC
clockskew = 900

# The following libdefaults parameters are only for Heimdal Kerberos.
v4_instance_resolve = false
v4_name_convert = {
host = {
rcmd = host
ftp = ftp
}
plain = {
something = something-else
}
}
fcc-mit-ticketflags = true

[realms]
TEST.TEST.LOC = {
kdc = dc.ad.test.loc
kdc = dc1.ad.test.loc
kdc = dc2.ad.test.loc
kdc = dc3.ad.test.loc
admin_server = dc.test.loc
}

[domain_realm]
.test.loc = AD.TEST.LOC

[login]
krb4_convert = true
krb4_get_tickets = false

[logging]
kdc = FILE:/var/log/krb5/krb5kdc.log
admin_server = FILE:/var/log/krb5/kadmind.log
default = SYSLOG:NOTICE:DAEMON
********************************************************************

libpam.winbind and libnss.winbind are installed.


Name resolution works (as before...):

host -t A dc.ad.test.loc
dc.ad.test.loc has address 123.456.789.208

getent hosts
127.0.0.1       localhost
123.456.789.244 test-fileserver3.test.test.loc test-fileserver3

Time is synchronized (as before...)

net join ads -U "Domainadmin" worked.

smbd, nmbd, winbind start sucessfully.
wbinfo -t and -p are successful.

But still no resolution. wbinfo -g and -u give no result. Also, getent 
passwd delivers only local accounts.

Log says (as expected) "Username AD\ps-15-16 is invalid on this system
[2016/04/16 18:52:45.713298,  3] 
../source3/auth/auth_generic.c:99(auth3_generate_session_info_pac)
   Failed to map kerberos principal to system user 
(NT_STATUS_LOGON_FAILURE)"

I tried, as read in the list, to change idmap config AD:backend = ad to 
rid. No change in results.

Anyone any idea? I'm momentarily at the end of mine.

Try removing 'winbind' from the shadow line, I have never used it, 
another user a few days ago was using it and was having similar problems 
to you, he removed windbind and reported back that everything was now 
working ok.

the 'ad' backend only works if your users have a unique uidNumber 
attribute, this number must be inside the range you set in smb.conf. 
Domain Users must also have a gidNumber.

'rid' is different, you do not have to add anything to AD

[Samba] After Update to 4.2, Samba is unusuable as member server / No user and goup resolution

Try it with a simple krb5.conf, or you have errors there, or you change to much
to anonimize..

 

Like :  

[libdefaults]

    default_realm = AD.TEST.LOC

    dns_lookup_kdc = true

    dns_lookup_realm = false

[Samba] After Update to 4.2, Samba is unusuable as member server / No user and goup resolution

Hello again,

no change here. But in the menatime I looked through the logfiles. 
Sorry, many of those lines are just cryptic to me. But maybe someone has 
an idea.

Thank you.

Again anonymized (domain names and IPs). Samba machine specific log seel 
below.

Connecting the passwd server and WINS seems to work.

Appearently errors:

Failed to setup SPNEGO negTokenInit request: NT_STATUS_INTERNAL_ERROR
ads reopen failed after error Time limit exceeded
enum_dom_groups ads_search: Time limit exceeded
Negative name query response, rcode 0x03: The name requested does not exist.

[Samba] After Update to 4.2, Samba is unusuable as member server / No user and goup resolution

Hello,

a reply in debianforum.de led me to:

client ldap sasl wrapping = plain

and with that setting at least wbinfo works.

But still my problems are not completely gone: On the filesystem level, 
AD users and groups are still not resolved. "Invalid user". But kinit 
"USER" works. Still have to try...

Regards, pgs

[Samba] FW: Domain member seems to work, wbinfo -u not (update7)

@Patrick Thanks, that helped. 
@Mathias, only 10.000 objects. 
>>  client ldap sasl wrapping = plain  << 
I've tested that on my members. 
4.2.10 
4.3.8 
4.4.1
4.4.2
wbinfo -u now work. 

Ok tested all 3 options of that settings. 
Tested als in the order, plain seal sign

Samba 4.2.10 (debian stable) 
   client ldap sasl wrapping = plain	wbinfo -u works. 
   client ldap sasl wrapping = seal		wbinfo -u fails
   client ldap sasl wrapping = sign		wbinfo -u fails
only plain works, en keeps working. 


Other server.
Version 4.4.2-LvB ( samba.org packages, own deb, based on debian 4.4.1 ) 
Default it fails, now the funny part. 
( default samba setting is sign ) 
We start with a NOT working wbinfo -u. 

Test with following changes. 
Try1) client ldap sasl wrapping = plain	wbinfo -u works. 
Try2) client ldap sasl wrapping = seal	wbinfo -u also works now. 
Try3) client ldap sasl wrapping = sign	wbinfo -u also works now.

Only the 4.4.2 now keeps working independed of the setting. 
Lunch first, i'll test the 4.3.8 also.

[Samba] FW: Domain member seems to work, wbinfo -u not (update8)( solved maybe?)

Ok.
New test, debian samba 4.2.10 ( all stock debian packages ) 

So others with 4.2.10 stock debian packages, please test also if below works. 


The file server on which (wbinfo -u) worked saterday, and not on Sunday until
now.


None of these three settings below are in the config and wbinfo -u fails. 


Now adding these settings !! one at the time !! 
And i reloaded samba and restarted winbind every time. 



    client ldap sasl wrapping = plain
    client ldap sasl wrapping = seal
    client ldap sasl wrapping = sign

Result in the end. 


I started with plain, wbinfo -u works, but first time a long delay before i see
the output, ( long is +4-5 sec)

Changed it to seal, wbinfo -u works


And back to the samba default "sign" which now also works. 
So seems fixed now. Strange.. 



Removed the client ldap sasl wrapping from the config. 
All still works. 



I'll check this server tomorrow again. 



 

Greetz, 

 

Louis
