Here is the error.
I’m using Samba LDAP.
Could not connect to accounts provider!!!
Please attach the output of the following commands on gist.github.com (or similar service)
account-provider-test dump
journalctl -M nsdc
Here is the dump file.
The journal is really long and appears truncated!
Could you attach also
systemctl status -M nsdc samba
systemctl status nsdc
Another useful test sometimes is
yum install -y nmap
nmap $(config getprop nsdc IpAddress)
@fasttech could be interested too… (Welcome back dear!) NethServer 7.5 RC1 released
The service is running, but can’t authenticate.
Ok, the nmap
command output says if all samba sub-processes are running correctly. Here’s the expected output:
$ nmap nsdc
Starting Nmap 7.60 ( https://nmap.org ) at 2018-06-07 09:19 CEST

Under some conditions related to upstream updates the kerberos-sec and kpasswd5 are missing and authentication stops working. Please check your.
Can you see the accounts list under “Users and groups” page?
This command should fail and show the error you see in the UI

Could you check also your DNS/SSSD/Kerberos config
config show dns
config show sssd

systemctl status dnsmasq
systemctl status sssd
cat /etc/krb5.conf
Nope, is not working…

@davidep Thanks for your time man.
Can’t make ping, Yum can’t resolve hosts… this machine doesn’t seems to be OK.
Did you try a reboot?
Please look also at
cat /etc/resolv.conf
[root@nethserver ~]# cat /etc/resolv.conf

Yes I rebooted the machine, but I have Ntop misterious traffic
Misterious traffic I think this machine is hijacked. I just upgrade the system from 7.4 to 7.5rc.
@hector Do you think the problem is solved? Is a reboot required?
Can you give more info about your installation?
Please attach the output of
yum history pkg-info nethserver-dc
last -50
No I couldn’t solve the problem, DNS querys are not working I’m planning to format the machine, Until 20 days I can’t touch the machine for that pourpose (web aplication working).
I have Ntop misterious Traffic in the machine I think that it is hijacked, dont know what to do.

Please edit the mrmarkuz repo file to disable it. Then attach the output of
yum check-update
Could you also attach
cat /var/lib/machines/nsdc/var/lib/samba/private/krb5.conf
mrmarkuz repo is disabled.
[root@nethserver ~]# yum check-update

Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - “Could not resolve host: mirrorlist.centos.org; Unknown error”
One of the configured repositories failed (Unknown),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64
(I can’t Access DNS servers, neither repos).
[root@nethserver ~]# cat /var/lib/machines/nsdc/var/lib/samba/private/krb5.conf
[libdefaults]
default_realm = AD.INFO2.UNICENTROBOGOTA.COM
dns_lookup_realm = false
dns_lookup_kdc = true
Are you sure the upstream DNS is reachable and works well?
Can you (temporarily) use another upstream DNS? like 8.8.8.8 or 8.8.4.4?
Yes is working in all the LAN (PFsense firewall) I changed all the Upstream DNS to 8.8.8.8 and it doesn’t work.
Do you have a web proxy? Can you disable it?
config show proxy
Nope, I was avaiable to update from 7.3 to 7.4 from 7.4 to 7.5 when this happens.
[root@nethserver ~]# config show proxy
