Can't use JDBC URL for multiple LDAPs

ColdFusion 8,0,1,195765 Enterprise (Trial)

We use Oracle OID (LDAP) instead of tnsnames.ora to resolve database connection strings. This is how I specify one LDAP JDBC URL. On the CF admin page, Server Settings, Java and JVM, ColdFusion Class Path is set to C:\oracle\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar. Under Data & Services, Data Sources, create a new source. Set JDBC URL to

jdbc:oracle:thin:@ldap://mdaoid1.mycompany.com:389/mdad2,cn=OracleContext,dc=mycompany,dc=com

where mdaoid1 is one of the two Oracle OID servers that resolve connection strings, and mdad2 is an entry in the two OID's sync'ed to each other. That works.

According to many sources based on Google search for "space separated LDAP URLs", I should be able to add another LDAP server separated by space. Now I append " ldap://mdaoid2.mycompany.com:389/mdad2,cn=OracleContext,dc=mycompany,dc=com" (no quotes, added to indicate leading space) to that string. Upon clicking Submit, I get

Connection verification failed for data source: orcl10g3
java.sql.SQLException: For input string: "389 ldap:"
The root cause was that: java.sql.SQLException: For input string: "389 ldap:"

(orcl10g3 is the CF data source name I'm creating) Some say I need to replace space with %20 in the double LDAP URL. With %20, I get error

Connection verification failed for data source: orcl10g3
java.sql.SQLException: Io exception: JNDI Package failurejavax.naming.InvalidNameException: Invalid name: mdad2,cn=OracleContext,dc=mycompany,dc=com ldap://mdaoid2.mycompany.com:389
The root cause was that: java.sql.SQLException: Io exception: JNDI Package failurejavax.naming.InvalidNameException: Invalid name: mdad2,cn=OracleContext,dc=mycompany,dc=com ldap://mdaoid2.mycompany.com:389

Question: How do I add more than one LDAP server to the JDBC URL so I can achieve failover and load balance?
