Placing DNs in Multi-Valued Attributes

Placing DNs in Multi-Valued Attributes

Problem



A Forum reader recently asked:



"I am writing a policy where I need to run a query to get a list of one or more DNs, then place those DNs as the values of a multi-valued attribute in my destination data source. How do I do this? Can I use the do-add-dest-attr-value action and just specify the 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?



The driver will load User objects into eDirectory from a JDBC data source. We have a custom multi-valued attribute on each of these users that lists a number of locations for which the user has some administrative responsibilities."



And here's the response from Father Ramon ...



Solution



You need to use do-for-each to iterate over the values you are expecting to get back. For example:



<do-for-each>
<arg-node-set>
<token-query class-name="Locality">
<arg-dn>
<token-parse-dn dest-dn-format="dest-dn" src-dn-format="ldap">
<token-text>o=foo, l=bar, dc=County, dc=Organizations,
dc=baz</token-text>
</token-parse-dn>
</arg-dn>
</token-query>
</arg-node-set>
<arg-actions>
<do-add-dest-attr-value name="xxx">
<arg-value>
<token-xpath expression="$current-node/@src-dn"/>
</arg-value>
</do-add-dest-attr-value>
</arg-actions>
</do-for-each>


If your custom attribute syntax is DN, then the above should work. If it is a string and you want it in LDAP format, then you'll want to change the value to something more like this:



<token-parse-dn src-dn-format="qualified-slash" dest-dn-format="ldap">
<token-xpath expression="$current-node/@qualified-src-dn"/>
</token-parse-dn>
