hi users,
I have a samba and sssd trying AD, it's 7.2 Linux.
That linux box is via sssd and samba talking to AD DC and win10 clients get
to samba shares, getent pass sees AD users, samba can get to DC's shares and
win10's clients shares, all good except...
smbclient @samba, in other words - to itself - fails
session setup failed: NT_STATUS_LOGON_FAILURE
and with smbclient -k
gss_init_sec_context failed with [Unspecified GSS failure. Minor code may
provide more information: Server cifs/[email protected] not found

Which realm is PRIVATE.DOM? What does
$ klist -k -t /etc/krb5.swir.ccnr.keytab
return?

and swir runs samba, but I'm trying to sssd together AD &
IPA, I should have mentioned.
From DNS perspective it's AD = ccnr.dom and IPA =
private.ccnr.dom, everything seems to resolve OK, both @AD
and @IPA ends.
And my sssd.conf:
------------
ipa_hostname = swir.private.ccnr.dom
chpass_provider = ipa
ipa_server = swir.private.ccnr.dom
ipa_server_mode = True
ldap_tls_cacert = /etc/ipa/ca.crt
#krb5_keytab = /etc/krb5.private.ccnr.keytab
[domain/ccnr.dom]
ad_domain = ccnr.dom
krb5_realm = CCNR.DOM
realmd_tags = manages-system joined-with-samba
cache_credentials = True
id_provider = ad
krb5_store_password_if_offline = True
default_shell = /bin/bash
ldap_id_mapping = True
use_fully_qualified_names = True
fallback_homedir = /home/%u@%d
access_provider = ad
auth_provider = ad
krb5_keytab = /etc/krb5.swir.ccnr.keytab

services = nss, sudo, pam, ssh
config_file_version = 2
domains = private.ccnr.dom, ccnr.dom
[nss]
memcache_timeout = 600
homedir_substring = /home
--------------
AD DC (to which shares smbclient @swir can get to) shows:

CN=SWIR,OU=private,DC=ccnr,DC=dom:

SPNEGO(gse_krb5) creating NEG_TOKEN_INIT failed:
NT_STATUS_INTERNAL_ERROR
Failed to setup SPNEGO negTokenInit request:
NT_STATUS_INTERNAL_ERROR
session setup failed: NT_STATUS_INTERNAL_ERROR
what I see in last one above is -
cifs/[email protected]
I've just realized, for some reason, and maybe a valid one,
smbclient don't do - cifs/[email protected]
which is in the keytabs.
but smbclient fails without -k which I understand should
then use a password and should be sufficient to authenticate.
many thanks Sumit,
L.

here is a snippet from smb.conf which I thought has relevance, I set it up
following samba sssd wiki.
security = ads
realm = CCNR.DOM
workgroup = CCNR
kerberos method = secrets and keytab
dedicated keytab file = /etc/krb5.swir.ccnr.keytab
client signing = auto
client use spnego = yes
encrypt passwords = yes
password server = ccnr-winsrv1.ccnr.dom
netbios name = SWIR
template shell = /bin/bash
template homedir = /home/%D/%U
preferred master = no
dns proxy = no
wins server = ccnr-winsrv1.ccnr.dom
wins proxy = no
inherit acls = Yes
map acl inherit = Yes
acl group control = yes
and in samba log:
domain_client_validate: Domain password server not available.
I've tried samba user list, dead silence.
many thanks,
L.
