<samba:parameter name="client ldap sasl wrapping" context="G" type="string" advanced="1" xmlns:samba="http://www.samba.org/samba/DTD/samba-doc"> <description> <para> The <smbconfoption name="client ldap sasl wrapping"/> defines whether ldap traffic will be signed or signed and encrypted (sealed). Possible values are <emphasis>plain</emphasis>, <emphasis>sign</emphasis> and <emphasis>seal</emphasis>. </para> <para> The values <emphasis>sign</emphasis> and <emphasis>seal</emphasis> are only available if Samba has been compiled against a modern OpenLDAP version (2.3.x or higher). </para> <para> This option is needed in the case of Domain Controllers enforcing the usage of signed LDAP connections (e.g. Windows 2000 SP3 or higher). LDAP sign and seal can be controlled with the registry key "<literal>HKLM\System\CurrentControlSet\Services\</literal> <literal>NTDS\Parameters\LDAPServerIntegrity</literal>" on the Windows server side. </para> <para> Depending on the used KRB5 library (MIT and older Heimdal versions) it is possible that the message "integrity only" is not supported. In this case, <emphasis>sign</emphasis> is just an alias for <emphasis>seal</emphasis>. </para> <para> The default value is <emphasis>plain</emphasis> which is not irritable to KRB5 clock skew errors. That implies synchronizing the time with the KDC in the case of using <emphasis>sign</emphasis> or <emphasis>seal</emphasis>. </para> </description> <value type="default">plain</value> </samba:parameter>
