Hi there,
I am struggling with samba4 and the internal dns and kerberos.
It seems that DNS is the problem.
When I aske for kerberos dns entrys on my workstation, I get this
(11.22.33.202 is the samba4 server):
root@lit2:~# dig _kerberos._udp.DOMAIN.LOCAL @11.22.33.202
; <<>> DiG 9.7.3 <<>> _kerberos._udp.DOMAIN.LOCAL @11.22.33.202
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 3733
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;; WARNING: recursion requested but not available
;; QUESTION SECTION:
;_kerberos._udp.DOMAIN.LOCAL. IN A
;; Query time: 1 msec
;; SERVER: 11.22.33.202#53(11.22.33.202)
;; WHEN: Wed Sep 4 10:10:33 2013
;; MSG SIZE rcvd: 48
But if I ask the samba directly:
root@linsrv:~# samba-tool dns query 11.22.33.202 DOMAIN.LOCAL
_kerberos._udp ALL
Password for [Administrator@DOMAIN.LOCAL]:
Name=, Records=1, Children=0
SRV: linsrv.domain.local. (88, 0, 100) (flags=f0, serial=110, ttl=900)
root@linsrv:~# samba-tool dns query 11.22.33.202 DOMAIN.LOCAL linsrv ALL
Password for [Administrator@DOMAIN.LOCAL]:
Name=, Records=1, Children=0
A: 11.22.33.202 (flags=f0, serial=110, ttl=900)
It seems that the entries from the dns database don't get "propagated"
to the dns server and I tried a "samba_dnsupdate --verbose --all-names".
This is the result (with 'debug level = 10'):
root@linsrv:/usr/local/samba# samba_dnsupdate --verbose --all-names
