Installation#2b. Why do my web users experience very long delays and/or get mis-assigned to the default filter group when I try to use the Ident method of authentication?
In order to successfully use the Ident method of authentication, your entire internal network must pass port 113 traffic. Commonly the default configuration of firewall software on each individual computer causes a problem; in particular the firewall built into Windows by default blocks port 113 traffic to the local computer. Port 113 must be opened in every local firewall in order for you to use the Ident method of authentication successfully.
