[horde] Last Login not changing

[Rick Emery]

Using the latest CVS HEAD, my last login is stuck on Apr 4 (the database isn't
being updated). I've looked at the code, and it appears that this gets set in
horde/Auth.php, function setAuth. I've looked at the code, and added var_dump
and print calls throughout setAuth, but don't get any output from it.

Any ideas what I'm doing wrong, or how I could troubleshoot it?

Thanks in advance,
Rick
