a) Logon to the FDM application server
b) Launch the FDM Load Balance configuration
c) Click on the Authentication Providers tab
d) Highlight the OpenLdap/HSS provider and choose "Modify"
e) Click the "Logon Test' button and enter your uid/pwd and click OK
Is the logon test successful or do you receive an error? I am expecting an error.
At this point you would need to open a service request with Oracle to have an analyst take a look at your authentication provider setup and your environment to determine the cause. The type mismatch is caused from the inability to authenticate your user account with the provider.
