      Enable NTLM SSO but leave the subnet field blank. Test SSO does not work. Then specify a subnet, even 0.0.0.0/0, and SSO magically starts to work.

      Description

      The wording next to the Subnet field on the NTLM SSO setup page in Moodle (admin/auth_config.php) implies that specifying a subnet value is optional. It says "If set, it will only attempt SSO with clients in this subnet". The words "If set" imply that a subnet value is optional, but this is incorrect - specifying a subnet is mandatory else SSO will not work. In the http://moodle.org/mod/forum/discuss.php?d=186661#p813594 discussion Iñaki Arenaza explains very clearly that "if you don't specify a value in that field (left blank or just white space) NTLM will not work. In fact, Moodle won't even try to start using NTLM at all."

      The wording on the NTLM SSO setup page should be changed so that it explains clearly that a subnet value (or values) is mandatory.
