Hi, Mohit.
Please correct me if I'm wrong, but that's what is usually called "multi-tenancy", correct? Gluu doesn't support this feature. Implementing something like that would require a lot of deep customizations of oxTrust (Gluu's web UI). If you are really into it, Gluu's sources are open and you can study and extend the code. If you think you may need support during this project, you could consider some paid support plan, as such customizations are not covered by community support.
