>We have setup the server on windows but not able to find out how we can integrate Gluu with Secret Server
Do you mean your product ("Secret Server") was installed on windows? Otherwise, please elaborate (Gluu Server doesn't support Windows naturally).
Overall, assuming you're already familiar with SCIM (as protocol), it should be fairly simple to integrate your app with Gluu Server. I would recommend to start with protection mode set to "TEST" or "BYPASS, it will make calling SCIM endpoints easier as you won't need to deal with UMA (you can read about UMA [here](https://docs.kantarainitiative.org/uma/rec-uma-core.html)). You can find how to enable test mode [here](https://gluu.org/docs/gluu-server/4.4/user-management/scim2/#protection-using-test-mode).
I would suggest to read this doc page completely, it should answer most of your questions on how to use SCIM with Gluu: [link](https://gluu.org/docs/gluu-server/4.4/user-management/scim2/). You also could check [this article](https://gluu.org/docs/gluu-server/4.4/user-management/scim-scripting/) about SCIM custom scripts as an advanced reading topic.
Also, you specified 4.0 as your Gluu Server version - that's rather old, if it's a fresh installation, please use the most latest package available (4.4 I believe).
