Cisco VPN Server 3000 + Radius + LDAP = heeelp!!

[Osvaldo Campos M. - Administrador Red STI]

Hi...

Thanks for your answer Leonardo but, if I define the groups in the Cisco 
VPN Server, it will be enough with knowing the password of other defined 
group's to obtain an address from a group to which I don't really 
belong. I.e., if Sale's user know password of Development group, will 
can receive an Development address. 
    
For this reason it is that I should assign the address according to the 
value of the attribute LDAP, because this value identifies user's type 
and, therefore, the address that should have.

Other ideas for this, please??
