[Samba] Developed an issue with Samba File Server integrated with Samba-AD
Hi,
We have been using Samba File Server (Version 4.3.11 Ubuntu 14.04 LTS)
for quite sometime now. We recently installed Samba-AD (Samba AD Version
4.7.6) and made the file server a member of the Domain. Everything was
fine till around 11:15 am yesterday. We just added one more share folder
and gave access to three users and restarted Samba File Server services
- smbd, nmbd and winbindd - services and we lost the file server. None
of the domain user is able to login to file server and access their
shares. If we access the shares from a non-domain member PC, shares are
accessible.
File server when accessed asks for user name & password. Once the user
feeds his credentials, the login fails and again the file server will
ask for user credentials. This is really surprising.
We enabled log level 3 on both samba servers (File & AD Server) and we
see nothing with respect to this error.
Our smb.conf (samba file server) and Samba-AD (AD-smb.conf) are attached.
I am aware that Samba file server is very old and it's time to upgrade.
However, getting it back live is now critical for us.
Look forward for any guidance.
Thanks & Regards,
Anantha Raghava

Is winbindd still talking to the domain, eg 'wbinfo -P'?

Hello Andrew, Thanks for quick response. It looks like winbindd is not connecting to domain. wbinfo -P results in a failure. The actual result is: checking the NETLOGON for domain[WORKGROUP] dc connection to "" failed failed to call wbcPingDc: WBC_ERR_DOMAIN_NOT_FOUND -- Thanks & Regards, Anantha Raghava Do not print this e-mail unless required.

I would leave the domain, remove the netlogon share, remove all Samba .ldb and .tdb files (usually in /var/lib/samba), then rejoin the domain and restart the samba deamons (nmbd, smbd and winbindd), this will recreate all the Samba databases. If this doesn't work, add 'log level = 10' to smb.conf on the Unix domain member and see if anything pops out. I have however noticed this: DC smb.conf: realm = XXXX.COM workgroup = XXXX [netlogon] path = /usr/local/samba/var/locks/sysvol/exza.com/scripts Unix domain member smb.conf: workgroup = CSAEROTHERM realm = CSAEROTHERM.COM On the DC, the realm appears to actually be 'exza.com' but on the Unix domain member it is set to 'CSAEROTHERM.COM', these must match, yours don't.

I was just comparing the smb.conf of AD DC on exza.com server with that of CSAEROTHERM.COM. Since it was same, I just copied smb.conf from exza.com server and attached to the mail. I tried the your suggestion. I attempted to leave domain. it resulted in: root at samba-64:/var/lib/samba# net ads leave -U administrator No realm set, are we joined ? & If I try to join the domain, it results in : root at samba-64:/var/lib/samba# net ads join -U administrator Host is not configured as a member server. Invalid configuration. Exiting.... Failed to join domain: This operation is only allowed for the PDC of the domain.> > Rowland >Regards, Anantha Raghava
