This documentation helps you to troubleshoot problems users can encounter when running Samba as a member in an Active Directory (AD) forest or NT4 domain.
Setting the Samba Log Level
For details, see Setting the Samba Log Level.
The net
Command Fails to Connect to the 127.0.0.1
IP Address
Using the default settings, the net
command connects to the 127.0.0.1
IP address. If Samba is not listening on the loopback interface, the connection fails. For example:
To fix the problem, configure Samba to additionally listen on the loopback interface. For details, see Configure Samba to Bind to Specific Interfaces.
Alternatively, to temporarily work around the problem, pass the -I IP_address
or the -S host_name
parameter to the net
command.
getent not Finding Domain Users and Groups
Are you running getent passwd
or getent group
?Using these commands without winbind enum users = yes
and windbind enum groups = yes
in smb.conf
will not display any Domain users and groups.Adding the lines has a downside, it slows things down and the more users and groups you have, the slower things can get, so you should only add these lines for testing purposes.
If getent passwd demo01
doesn't return anything, try
if that works but the former doesn't you may need to add the following line to your smb.conf file
Troubleshooting the Domain Join Procedure
No DNS domain configured. Unable to perform DNS Update.
When joining a host to an Active Directory (AD), the net
command fails to update the DNS:
Note, that the join was successful and only the DNS updated failed.
After the client was joined to the domain, the net
command look up the fully qualified domain name (FQDN) using name service switch (NSS) libraries. If the FQDN can not be resolved, for example using DNS or the /etc/hosts
file, the DNS update fails.
To solve the problem:
- Add the IP address and FQDN to the
/etc/hosts
file. For example:
- Run the
net ads join
command again.
If dynamic DNS updates still fail, verify on the AD DNS server that dynamic updates are working.
DNS Update failed: ERROR_DNS_UPDATE_FAILED
When joining a host to an Active Directory (AD), the net
fails to update the DNS:
Note, that the join was successful and only the DNS updated failed.
To solve the problem:
- Verify on your Samba domain controller (DC), if dynamic DNS updates are working. For details, see Testing Dynamic DNS Updates.
- Run the
net ads join
command again.
DNS Update failed: ERROR_DNS_GSS_ERROR
When using the BIND9_DLZ
back end, dynamic DNS updates can fail because of an incorrect Kerberos setup on the AD domain controller (DC) running the DNS server:
To solve the problem, see Reconfiguring the BIND9_DLZ Back End.
gss_init_sec_context failed with: Miscellaneous failure: Clock skew too great
When joining a host to an AD, the net
command fails with the following error:
Kerberos requires a syncronised time to prevent replay attacks. The local time must not differ more than 5 minutes to the DC.
To fix, set the correct time and run the net ads join
command again.
For further details, see Time Synchronisation.
Failed to join domain: failed to find DC for domain SAMDOM - Undetermined error
When joining a host to an Active Directory (AD), the net
command fails to locate the domain controller (DC):
Samba uses DNS requests and broadcasts to locate DCs when joining a domain. If both methods fail, the failed to find DC for domain SAMDOM - Undetermined error
error is displayed.
For a short term solution, you can pass the '-S' parameter and the name of a DC to the command. For example:
However, a correct DNS configuration is important in an AD. To avoid future problems based on an incorrect DNS configuration, set up your DNS resolver configuration correctly. For details, see Linux and Unix DNS Configuration.
Winbind and Authentication Problems
The getent
Utility Is Unable to List All Domain Users or Groups
If the getent
utility is able to list individual domain users or groups but the getent passwd
or getent group
command fail to list all domain users or groups:
- Verify that the name service switch (NSS) is able to use the
libnss_winbind
library. For details, see libnss_winbind Links. - Enable the following parameters in your
smb.conf
file:
- For performance reasons, it is not recommended to enable these settings in environments with a large number of users and groups.
- Reload Samba:
Connections to a Samba Domain Member Fail After Adding an includedir
Statement to the /etc/krb5.conf
File
When connecting to a Samba Active Directory (AD) domain member, the connection fails and the following error is logged, if the log level
parameter in the [global]
section of the smb.conf
file is set to 3
or higher:
The connection fails, because Samba is unable to process includedir
statements in the /etc/krb5.conf
file.
Note, that updating Kerberos packages on your operating system can automatically add this statement to enable the inclusion of configuration snippets. For example, when updating a Samba AD domain member with an unmodified /etc/krb5.conf
file from Red Hat Enterprise Linux 7.2 to 7.3, the includedir
statement is automatically added and clients fail to connect to the Samba domain member.
To work around the problem, remove the includedir
statement from the /etc/krb5.conf
file.
For further details, see Bug #12488.
Currently, we do not have content here.
serval years ago,I built freeradius server in centos 6 work with active directory. It works perfect with wifi authortication and ikev2 vpn authortication. But recently days, I found a bug that the radius server can not limit user access to a group in AD. So I’m trying to build a new freeradius server in debian 10. After a week work.At last I figure it out.
Install Software and configuration
First thing first, We need install a debian 10 server on your virtualization platform. currently, I installed a debian server on proxmox ve platform.

Change Debian settings
- Change hostname
- Sync NTP time with domain controllerInstall chrony
restart chrony service and force update times
Install samba and winbind and let Debian Host joined domain
- Install samba,winbind,krb5-user
- config samba config file
In [global]
section, change settings form
to
- Modify
/etc/nsswitch.conf
Change settings:
to
- Modify
/etc/krb5.conf
Restart OS
Join domain
Restart samba and winbind service
Testing samba AD authentication:
- Using winbind:
You will get the following message if everything is correct:
- Using ntlm_auth:
Then you will got success message:
Install freeradius
Install freeradius
Grant permission for
freerad
user on winbind’s socket:Change MACHAP to use ntlm_auth:
change
Change module mschap :
Change eap config.
Change settings of
default_eap_type
.to
Then restart freeradius service
Change
/etc/freeradius/3.0/sites-enabled/default
and/etc/freeradius/3.0/sites-enabled/inner-tunnel
Configure RADIUS client
restart service of freeradius
Test FreeRADIUS and MSCHAP:
The results will be like:
Configure freeradius-ldap Auth with AD
To limited to auth a AD group, we need to config freeradius auth with ldap.
- Install freeradius-ldap
Edit config
- edit
/etc/freeradius/3.0/mods-available/ldap
- create a link to mode-enable
- edit
/etc/freeradius/3.0/sites-available/default
- Restart freeradius service

- Change MACHAP to use ntlm_auth:
change
Install mysql,daloradius to make management freeradius with web access
- Install mariadb database
