restrict user access to queues

[#1]

Hi,

How can i restrict user access to specific queues especially when one user can use multiple queues but a few users can use only one queue ... I have seen how to give access to Groups but is it same for userid's as well? i mean to say:

User1 can access QueueA & QueueB & QueueC

User2 can only QueueA

User3 can only access QueueC
