Within a policy, I need to run a query to get a set of DNs and place those
DNs as the values of a multi-value attribute. I'm not sure how to go about

Here is the query that I'm running:
<token-query class-name="Locality">
<token-parse-dn dest-dn-format="dest-dn" src-dn-format="ldap">
<token-text xml:space="preserve">o=Allegheny Co 911, l=Allegheny,
dc=County, dc=Organizations, dc=jnet</token-text>
<token-text xml:space="preserve">DN</token-text>

Can I use a do-add-dest-attr-value action and specify this query as the
values to add, or do I need to place the results of the query in a local
variable and do something with that, or something else?

Thanks for your help!
