Trying to set the CN attribute to a different value.
So I am using:

<do-set-dest-attr-value class-name="Group" name="CN">
<arg-value>
<token-local-variable name="newcn"/>
</arg-value>
</do-set-dest-attr-value>

Yet I end up with the old value also.
> <add class-name="Group" dest-dn="groupname30" event-id="id8ref1#20070410131803#1#1" qualified-src-dn="dc=com\dc=willeke\OU=groups\CN=groupname30x-xxxx" src-dn="\DMTTREE\com\willeke\groups\groupname30x-xxxx" src-entry-id="40462">
> <add-attr attr-name="CN">
> <value naming="true" timestamp="1176211083#15" type="string">groupname30x-xxxx</value>
> </add-attr>
> <add-attr attr-name="gidNumber">
> <value timestamp="1176211083#61" type="int">627</value>
> </add-attr>
> <add-attr attr-name="CN">
> <value>groupname30</value>
> </add-attr>
> </add>


What am I missing?
Thanks
