Since using Moodle we've authenticated against LDAP servers which has worked flawlessly...... until late last week.
I'm not saying the problem is related to LDAP auth at all, and the same thing happens on our network, and also from home which leads me to believe it's Moodle/the Moodle server that's spat the dummy out.
As far as I'm aware, nothing has changed with the server/Moodle to cause these issues. Anyhow, down to what the issue is!
When logging in, the server has always used NTLM perfectly. However, of late it now produces a dialog login box saying "Authentication required".
Why might this be?
