This “may” be an issue with person directory. Don’t know yet, but your other 
option for now would be to have 2 DAOs and merge the result together 
finally.



What version of person directory is this by the way? Can you dulicate the 
problem with the latest?

Subject: [cas-user] Resolving attirbutes dao results in "no value specified 
for parameter 2"



Hello I am using singleRowJdbcPersonAttributeDao to resolve principal 
attributes defined as:



singleRowJdbcPersonAttributeDao

                    
class="org.jasig.services.persondir.support.jdbc.SingleRowJdbcPersonAttributeDao">

                      <constructor-arg index="0" ref="dataSourceA" />

                      <constructor-arg index="1"

                      value="(SELECT a, b,  c , d

                                              FROM u WHERE {0}

                                  UNION

                                              (SELECT a, b ,c d

                                              FROM r WHERE {0})" />

                      <property name="queryAttributeMapping">

                                  <map>

                                              <entry key="username" 
value="id" />

                                  </map>

                      </property>



And get SQLException->No value specified for parameter 2



NO replacement for second {0}, so I am not able to use this query.



Is there any reason for the behaviour of this implementation?



Regards Manfredo
