Hi Kartik, First, please check [how to ask question in support portal](https://support.gluu.org/docs/user-guide/how-to-ask/), if you just search in support portal with your keywords, you might find relevant community tickets already which will help you to speed up the whole implementation without even asking question to anyone. As for example, I did a quick 'access control' searching in our support portal and here is what I am getting. Screenshot attached. Second is, [UMA](https://www.gluu.org/docs/gluu-server/4.2/admin-guide/oxtrust-ui/#uma) which is what you are looking for.

First, Thanks Mohib for explaining me correct way how to raise tickets specially with gluu support. Second , i am looking for functionality which directly allow or restrict user from using specific client something similar to azure ad. i know about UMA and its not that direct as azure ad or google oidc. Anyway, Thanks for your quick reply.
