Summary

0015841: System fails to initialize the domain with missing NIC

Description

The Windows Networking module will not initialize if an interface is missing.

The initialization system should detect this condition and throw an exception early if /etc/samba/smb.conf contains 'interfaces = lo' only or 'interfaces = '

Steps To Reproduce

On a new system, configure the networking for gateway mode and configure from the External interface.

For the LAN interface, configure on DHCP and NEVER have it connected to a DHCP server source (ie. unconfigured)

Install and configure the accounts manager, OpenLDAP. Attempt to initialize the system. The /var/log/system log will have a similar log:

Jul 20 11:33:27 localhost samba: initializing Samba system
Jul 20 11:33:27 localhost samba: setting winadmin password
Jul 20 11:33:27 localhost samba: setting netbios name and workgroup: MyServer - TESTDOM
Jul 20 11:33:28 localhost samba: setting mode to PDC

Jul 20 11:34:59 localhost engine: exception: debug backtrace: /usr/sbin/app-samba-initialize (161): initialize_samba_as_master_or_standalone

If running the init from command line you will get:

[root@gateway mode]# /usr/sbin/app-samba-initialize
Server name (e.g. SERVER1): MyServer
Password: The following settings will be used to set up the Samba Directory

Mode: master

This is due to the fact that nmb cannot start without an interface:

[root@gateway ~]# systemctl status nmb
