Hello all, I've got a query for the networking types. I'm currently trying to get a wiki to LDAP authentication. Despite my best attempts it keeps failing. I can't understand the following. Some commands can resolve the ip address of internal servers when using there FQDN while others cannot. This is all within a Windows network. The server I'm trying to configure is Debian Squeeze. I am wondering if this might be why the LDAP authentication is not working. Any thoughts? Cheers, Chris ############## Find the ip address of thesun.tesla.local ############## wikiserver:~# dig thesun.tesla.local ; <<>> DiG 9.7.3 <<>> thesun.tesla.local ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 45615 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;thesun.tesla.local.
