Now, I have :
* a queue for our IT staff (10 agents), let's call it "ITqueue". It belongs to group "IT".
* 300 customers in our ldap backend, which all belong to group "Clients" (    $Self->{CustomerGroupAlwaysGroups} = ['Clients']; )

I would like to give these customers read and create rights on the "ITqueue", but can't figure how. I think I should associate them all to a role ("Client") that would have ro & create rights on group "IT", but how would I automatically give this role to all these 300 customers ?
