samba - Feb 2014 - Change Operating System Version Number

Hello,

Apologies if this has been asked before but I can't seem to find any
reference.

I was wondering if it is possible to change the advertised operating system
version that Samba 4 reports?

For example if you browse to the Samba 4 AD account using the WIndows AD Users
and Computer utility and right click on the Samba 4 server, under the Operating
System Tab the Name will appear as Samba and the version will appear as the
current Samba Version. As I built from source this is appearing as 4.1.4.

Is it possible to change this to something like 5 or 6 or even 7 ? The reason I
want to do this is some programs, notably Exchange 2010 check the AD controller
before installing. While the Functional Level is correct the Exchange Installer
detects the OS as version 4.1.4 or whatever and bomb out.

I've tried manipulating the server string parameter in smb.conf but to no
avail.

Many thanks in advance.
Robert

Do you mean the operationSystem and operationSystemVersion attribute of 
the domain controllers machine account?

This is always set to "Samba" and the version you run at 
provisioning/classicupgrade time:

# ldbsearch -H ldap://DC1 -U administrator "cn=DC1"
Password for [SAMDOM\administrator]
# record 1
...
operatingSystem: Samba
operatingSystemVersion: 4.0.5



You can change this with
# ldbedit -H ldap://localhost -Uadministrator -b "CN=DC1,OU=Domain 
Controllers,DC=samdom,DC=example,DC=com"



As the version always shows the one you used at provisioning time and 
never changes, I _guess_, that it's save to change it. But without any 
warranty. :-)
