Red Hat Bugzilla – Bug 864832
smbclient ignores rdns setting in krb5.conf
Last modified: 2014-02-05 07:32:05 EST
Description of problem:
Unlike other applications doing GSSAPI/Kerberos authentication to a server smbclient does not respect the rdns setting in /etc/krb5.conf.
rdns If set to false, prevent the use of reverse DNS resolution when
translating hostnames into service principal names. Defaults to
true. Setting this flag to false is more secure, but may force
users to exclusively use fully qualified domain names when
authenticating to services.
smbclient should respect rdns setting in /etc/krb5.conf.
It looks like samba creates and uses its own private and probably per domain config file in /var/lib/samba/smb_krb5 directory. It messes my setup of allowed encryption types.
I guess this is the file you need to chase as well.
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '18'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 18's end of life.
Thank you for reporting this issue and we are sorry that we may not be
able to fix it before Fedora 18 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior to Fedora 18's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
