Can't login since CVS update

[Dan Wilson]

I updated from CVS yesterday (and again this morning)... 

But now, I can't login to either a remote pop or local imap.  I've updated 
all my config files.  And verified repeatedly that I transfered the setting 
to the new .dist files correctly. 

I don't get anything in the logs (either horde.log or maillog).  It doesn't 
even say auth failed or anything. 

The really weird thing is that I can run the IMP tests (imp/test.php) and 
login to my IMAP server from there... and it let's me know that there are 
[n] number of emails in there, but I can't login to the blasted account 
through the normal IMP login. And then I can see activity in my maillog. 

Has anyone been having similar problems?  Can anyone help me troubleshoot 
this?
