Subject: MDL-9399 auth/ldap: NTLM redirect only on initial GET
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=0a1c2f4a43daae89559f317962af103dbe6d5853;p=moodle.git

MDL-9399 auth/ldap: NTLM redirect only on initial GET

We only want to redirect when users are being shown the login page (on
GET) but not when users are POSTing to it, actually trying to login.
