When you use the LDAP Search component in LiveCycle ES and set up the component (with the refresh or build buttons), you receive the following error:
Cannot instantiate class com.sun.jndi.ldap.Ldap.CtxFactory
The initial_context_factory parameter (in the deployment settings of this component) has been changed during the migration process by mistake from null to com.sun.jndi.ldap.Ldap.CtxFactory.
Change this parameter to the correct value: com.sun.jndi.ldap.LdapCtxFactory.
When a null value was used in LiveCycle 7, the server interpreted it as com.sun.jndi.ldap.LdapCtxFactory by default. This issue no longer happens in LiveCycle ES, so you cannot use null values for this parameter.
