Hi @Venkatachalam, Rohit (Partner) • Thank you for reaching out.
You need to make sure that User assignment required?
is set to YES under the properties of the enterprise applications. If this option is set to NO, all users in Azure AD can sign in to the Enterprise Application, regardless of whether users are added to the user list of the enterprise application or not. In either case, users won't automatically get assigned to the application.
Once you set User assignment required?
to YES, only the users who are added to the user list of the enterprise application can access the application.
Please refer to Manage user assignment for an app in Azure Active Directory, for more details.
