When using the action while in mysql driver not thing is send on the driver,
means the trace file is 0 bytes.
I'm using the rule

<rule>
<description>On create User in asterisk save ou grup</description>
<conditions>
<and/>
</conditions>
<actions>
<do-while>
<arg-conditions>
<and>
<if-op-attr mode="src-dn" name="Group Membership"
op="equal">NO\Telefoni\Organisatorisk grupper\IT</if-op-attr>
</and>
</arg-conditions>
<arg-actions>
<do-set-src-attr-value name="Asterisk-Old-Ou-Grp">
<arg-value>
<token-local-variable name="current-node"/>
</arg-value>
</do-set-src-attr-value>
</arg-actions>
</do-while>
</actions>
</rule>

If I disabel the rule everything is working
