No, I should have expanded on that, what I meant was, is one or other of 
the DC or Unix domain member running in a docker container ?

I don't understand it either, you seem to be running the same as I am, 
but you are using NTLM in the search (SASL/NTLM authentication started) 
and I am using kerberos:

SASL/GSS-SPNEGO authentication started
SASL username: rowland at SAMDOM.EXAMPLE.COM

I am using Devuan 3 (Debian 10 minus systemd) on the DC and Unix domain 
member and it works.

However, I have just discovered it doesn't work from Unix domain member 
running on Raspbian:

pi at raspberrypi:~ $ ldapsearch -h dc4.samdom.example.com -U 'rowland' -W 
-b 'cn=Users,dc=samdom,dc=example,dc=com'
Enter LDAP Password:
SASL/GSS-SPNEGO authentication started
ldap_sasl_interactive_bind_s: Local error (-2)
     additional info: SASL(-1): generic failure: GSSAPI Error:  An 
unsupported mechanism was requested (unknown mech-code 0 for mech unknown)

Same command against the same DC and it doesn't work :-\

It is still trying to use Kerberos though.

I will get back to you when I find out why it isn't working.
