[imp] IMP Login Issues With Internet Explorer

[Adam Tauno Williams]

Horde 5.2.3 / IMP 6.2.4
Firefox 31.20.0
Internet Explorer 11.0.13

Logging into my instance with Firefox [or Epiphany] works without
incident.

Logging into Internet Explorer fails, it just says authentication fails
and goes back to the login page.

Anyone else seen this?  There appears to be no errors, warnings, etc...
