Problema com CUPS

[EduTacara]

Olá, estou montando um servidor de impressão e tenho que colocar a permissões para usuarios, usuarios comuns só podem imprimir e usuario admins e suporte pode gerenciar e cancelar os jobs. Na hora de autenticação do CUPS eu só consigo acessar com o usuario root, mas preciso fazer a autenticação com o admin e o suporte. Já tentei adicionar os usuarios ao grupo lpadmin e não du certo.

Aque está a minha configuração.
