<samba:parameter name="tls verify peer"
context="G"
type="enum"
enumlist="enum_tls_verify_peer_vals"
xmlns:samba="http://www.samba.org/samba/DTD/samba-doc">
<description>
<para>This controls if and how strict the client will verify the peer's certificate and name.
Possible values are (in increasing order):
<constant>no_check</constant>,
<constant>ca_only</constant>,
<constant>ca_and_name_if_available</constant>,
<constant>ca_and_name</constant>
and
<constant>as_strict_as_possible</constant>.</para>
<para>When set to <constant>no_check</constant> the certificate is not verified at
all, which allows trivial man in the middle attacks.
</para>
<para>When set to <constant>ca_only</constant> the certificate is verified to
be signed from a ca specified in the <smbconfoption name="tls ca file"/> option.
Setting <smbconfoption name="tls ca file"/> to a valid file is required.
The certificate lifetime is also verified. If the <smbconfoption name="tls crl file"/>
option is configured, the certificate is also verified against the ca crl.
</para>
<para>When set to <constant>ca_and_name_if_available</constant> all checks from
<constant>ca_only</constant> are performed. In addition, the peer hostname is verified
against the certificate's name, if it is provided by the application layer and
not given as an ip address string.
</para>
<para>When set to <constant>ca_and_name</constant> all checks from
<constant>ca_and_name_if_available</constant> are performed.
In addition the peer hostname needs to be provided and even an ip
address is checked against the certificate's name.
</para>
<para>When set to <constant>as_strict_as_possible</constant> all checks from
<constant>ca_and_name</constant> are performed. In addition the
<smbconfoption name="tls crl file"/> needs to be configured.
Future versions of Samba may implement additional checks.
