[Samba] Joining Samba4 to Domain as DC with Small Business Server 2008 - error with Exchange ldap entries

[Paul Rogers]

Hi All

I'm trying to join and existing Windows domain with Samba4, on Centos 6.5
Final.  I initially tried with the Centos rpm's but it seems the
samba-tools didn't exist so I am now using the rpms from SerNet Enterprise
SAMBA.

The current DC is a Windows Small Business Server 2008 that provides file,
print, DNS, DHCP, AD and MS exchange/Outlook Web access.

The domain Company.local is a substitute for the real domain name [Company
name].local

I have installed the server using the instructions here:

https://wiki.samba.org/index.php/Samba_AD_DC_HOWTO

The rpm versions are:

sernet-samba-libwbclient-devel-4.1.4-7.el6.x86_64
sernet-samba-ad-4.1.4-7.el6.x86_64
sernet-samba-client-4.1.4-7.el6.x86_64
sernet-samba-debuginfo-4.1.4-7.el6.x86_64
sernet-samba-common-4.1.4-7.el6.x86_64
sernet-samba-4.1.4-7.el6.x86_64
sernet-samba-libs-4.1.4-7.el6.x86_64
sernet-samba-winbind-4.1.4-7.el6.x86_64
sernet-samba-libsmbclient0-4.1.4-7.el6.x86_64
sernet-samba-libsmbclient-devel-4.1.4-7.el6.x86_64

I have then started following the instructions here:

https://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC

At the point at which I run the command:

/usr/bin/samba-tool domain join Company.local DC -Uadministrator
--realm=company.local

I receive the error message:

A search on the error message turned up the following:

but no response after Andrew Bartlett's initial query.

I have run the suggested query:
