The need for this has now passed, but I did get SecretStore working with form fill. I followed the Access Manager documentation and it worked. I had to configure the credential profile to use the user store for shared secrets. The form fill created secrets as named but with the prefix "Cred-SS." or something like that, in the user store (i.e. eDirectory).
Thanks for your help. I am always amazed at what you can do with NetIQ/Novell products and this forum is so useful.
