Assign user to a realm.

[Deepansha Gaur]

Hi team,

I am trying to assign VLANs to different realms, and only a few users to be
part of a given realm.
E.g.: user1 and user2 are part of @staff and should be assigned VLAN 123
 user3 and user4 are part of @student and should be assigned 98
If a user is not part of a realm, he should be denied.

Could you please help me on how I can assign a user to a realm?  Thanks for
your help.

Regards,
