samba - Oct 2019 - Unable to initialize messaging context!

Hello, 

I am getting this when trying to run testparm and I'm also unable to start
the samba daemon. I am trying to set up a AD DC. This is a fresh install of
CentOS 7 minimal with the dependency script from the wiki run. The version is
4.11.2 and was successfully compiled. I believe the two issues are related but
I'm unable to find anything on google that indicates what could be the
problem.

When running the samba daemon with -i this is the output I get: 

exit_daemon: daemon failed to start: Samba failed to setup parent messaging,
error code -1073741801

CentOS 7 Minimal 
All dependencies installed via script from the wiki 
Compiled from source 

smb.conf: 
# Global parameters 
[global] 
dns forwarder = 8.8.8.8 
netbios name = DC1 
realm = CORP.EXAMPLE.COM 
server role = active directory domain controller 
workgroup = CORP 

[sysvol] 
path = /var/locks/sysvol 
read only = No 

[netlogon] 
path = /var/locks/sysvol/corp.example.com/scripts 
read only = No 


Any help would be appreciated. 

Thanks, 
Rich

The post subject could point to your error, it happens when you try to 
do something on Samba as a normal user when it it should be done as root 
or by using sudo.

Try running the command with 'sudo' at the beginning and '-d3'
at the end.

As you have compiled Samba yourself, what was your configure line ?

Contrary to best practices, on my boxes I'm always root so it is doing this
when run as root.  I'm getting the error for the daemon also when run as a
system service in systemd.

Configure line:  
./configure \
--disable-cups \
--without-ldb-lmdb \
--prefix=/opt/samba \
--sysconfdir=/etc/samba \
--localstatedir=/var \
--with-systemd \
--systemd-install-services \
--with-logfilebase=/var/log/samba

Here is the command run with -d3:
#> ./samba -i -d3
lpcfg_load: refreshing parameters from /etc/samba/smb.conf
samba version 4.11.2 started.

Unable to create directory /var/lock for file msg.lock. Error was File exists
exit_daemon: daemon failed to start: Samba failed to setup parent messaging,
error code -1073741801

Could be the /var/lock thing but the directory exists and with root privileges
it should be able to create msg.lock.  Not sure why that is happening.

Thanks,
