Live Upgrade
To upgrade the schema version on a running Samba installation to 2012_R2, use this command:
> samba-tool domain schemaupgrade
Note: This tool only works from 2008 R2. In order to upgrade from earlier versions, the ldf files must be manually sourced from the Windows adprep tool and run with the --ldf-file= option.
Determine the AD Schema Version on a Samba DC
To determine the Active Directory (AD) schema version on a Samba domain controller (DC):
Replace "dc=samdom,dc=example,dc=com" with your own domain
# ldbsearch -H /usr/local/samba/private/sam.ldb -b 'cn=Schema,cn=Configuration,dc=samdom,dc=example,dc=com' -s base objectVersion # record 1 dn: CN=Schema,CN=Configuration,DC=samdom,DC=example,DC=com objectVersion: 47 # returned 1 records # 1 entries # 0 referrals
Determine the AD Schema Version on a Windows Client or Server
dsquery
To determine the Active Directory (AD) schema version from the Windows command line:
> dsquery * "cn=Schema,cn=Configuration,dc=samdom,dc=example,dc=com" -scope base -attr objectversion objectversion 47
PowerShell
To determine the Active Directory (AD) schema version from the Windows PowerShell:
> Get-ADObject (Get-ADRootDSE).schemaNamingContext -properties objectVersion DistinguishedName : CN=Schema,CN=Configuration,DC=contoso,DC=com Name : Schema ObjectClass : dMD ObjectGUID : 92801cf6-f22d-4b7f-ba70-00af98790881 objectversion : 47
