Hi, I am using squid-2.5.STABLE-13 version built with delay pools. I am having some doubts in configuring delay pools. 1. Is it possible to use LDAP group based authentication with delay pools (meaning :- assigning LDAP group acls with delay pools already configured)? If so, which delay class (1 or 2 or 3) can be used? 2. To limit bandwidth to the network and also to the individual users, delay class 3 can be used, right? Here can i use A class network or only B class network should be used? And can i use the mixture of both A class and B class networks? Thanks for your help. Thanks Selvi
