Please help with SQL developer database connection using connection type LDAP. I get above error message .
The database is 11gR2
I created an Advanced Connection Type with a Custom JDBC URL similar to the following that I found on google( jdbc:oracle:thin:@ldap://ldapsrv:389/testdb1,cn=OracleContext,dc=idevelopment,dc=info ) as
jdbc:oracle:thin:@ldap://ldap-srv.tomri.ac.uk:389/OID,dc=tomri,dc=ac,dc=uk
This is the entry of my LDAP.ora
DIRECTORY_SERVERS = (ldap-srv.tomri.ac.uk:389)
DIRECTORY_SERVER_TYPE = OID
DEFAULT_ADMIN_CONTEXT = "dc=tomri,dc=ac,dc=uk"

I will be grateful for your assistance
