Hi Rahul Sahu,
I am working with Vamsi and we were able to fix the SQL problem. The issue was that the plugin had a wrong SQL query, the format looked like MySQL syntax, once we changed to Oracle it worked fine.
Now we have another issue on the configuration form, more specifically the second tab called "SP Connector settings and Claims". It never saves the configuration and reset to the default values as follows.

All the other tabs are working fine but this one. We debugged using the Service Studio and it looks like it is a problem with the Form validation. For some reason it always returns "false".

We went through all the fields on the form and we are filling all the fields that is mandatory but the validation is always false. Any ideia what is going on?
Thanks!
Andre
