Description Noël Köthe 2014-01-23 14:51:40 UTC
Hello,

asking on samba@ without success ( https://lists.samba.org/archive/samba/2014-January/178043.html ). Hopefully it is OK to report this as documentation bug:

samba 4.1.4 on Debian

the samba-tool manpage says:
...
       -k KERBEROS|--kerberos=KERBEROS
           Use Kerberos
...

adding a dns record works as expected:
root@samba:~# samba-tool dns add localhost example.com www CNAME web.example.com 
Password for [administrator@EXAMPLE.COM]:
Record added successfully

Now trying to use the -k option:

# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: administrator@EXAMPLE.COM

Valid starting       Expires              Service principal
16.01.2014 14:32:30  17.01.2014 00:32:30  krbtgt/EXAMPLE.COM@EXAMPLE.COM
        renew until 17.01.2014 14:32:26

root@samba:~# samba-tool dns add localhost example.com www2 CNAME web.example.com -k
Usage: samba-tool dns add <server> <zone> <name> <A|AAAA|PTR|CNAME|NS|MX|SRV|TXT> <data>

samba-tool dns add: error: -k option requires an argument


root@samba:~# samba-tool dns add localhost example.com www2 CNAME web.example.com -k KERBEROS
Usage: samba-tool dns add <server> <zone> <name> <A|AAAA|PTR|CNAME|NS|MX|SRV|TXT> <data>

samba-tool dns add: error: invalid -k option value: KERBEROS

    dns_conn = dnsserver.dnsserver(binding_str, lp, creds)

Could the manpage describe what the -k option should be?

Thank you.

Tried '-k yes' and '--kerberos=yes' (without quotes, of course) as suggested at https://lists.samba.org/archive/samba/2014-January/178268.html and http://www.eenyhelp.com/answer/samba-samba-tool-kerberos-help-215840236.html. It fails with the following:


# samba-tool dns add localhost $(hostname -d) example a 192.168.0.1 --kerberos=yes

    dns_conn = dnsserver.dnsserver(binding_str, lp, creds)

(`kinit` was invoked OK right before). If I give an actual DNS name of the server instead of localhost, smaba-tool keeps asking for password. If I give '-U username%password', samba-tool works as expected with both localhost and a server name.
