8 <para>The value of the parameter (a string) is the Active
9 Directory functional level that this Domain Controller will claim
12 <para>Possible values are :</para>
15 <para><constant>2008_R2</constant>: Similar to Windows
16 2008 R2 Functional Level</para>
19 <para><constant>2012</constant>: Similar to Windows
20 2012 Functional Level</para>
23 <para><constant>2012_R2</constant>: Similar to Windows
24 2012 R2 Functional Level</para>
27 <para><constant>2016</constant>: Similar to Windows
28 2016 Functional Level</para>
32 <para>Normally this option should not be set as Samba will operate
33 per the released functionality of the Samba Active Directory
34 Domain Controller. </para>
36 <para>However to access incomplete features in domain functional
37 level 2016 it may be useful to
38 set this value, prior to upgrading the domain functional level. </para>
40 <para>If this is set manually, the protection against mismatching
41 features between domain controllers is reduced, so all domain
42 controllers should be running the same version of Samba, to ensure
43 that behaviour as seen by the client is the same no matter which
44 DC is contacted.</para>
46 <para>Setting this to <constant>2016</constant> will allow
47 raising the domain functional level with <command>samba-tool
48 domain level raise --domain-level=2016</command> and provide
49 access to Samba's Kerberos Claims and Dynamic Access
50 Control feature.</para>
52 <warning><para> The Samba's Kerberos Claims and Dynamic Access
53 Control features enabled with <constant>2016</constant> are
54 incomplete in Samba 4.19. </para></warning>
59 <!-- DO NOT MODIFY without discussion: take care to only update this
60 default once Samba implements the core aspects of Active
