problems with IMP / imapd

[Christopher Stein]

I am having trouble successfully logging in to IMP.

I am running:

MySQL-3.23.32
php-3.0.18
imp-2.2.4
imap-2000c
horde-1.2.3
apache-1.3.14
FreeBSD-4.1

This is the problem (from /var/log/messages): 

Feb  6 00:19:39 orvieto imapd[5353]: Login failure user=^A host=localhost
[127.0.0.1]
Feb  6 00:19:45 orvieto last message repeated 2 times
Feb  6 00:19:48 orvieto IMP[536]: FAILED 140.247.60.201 to localhost:143
as stein

It is not allowing me to log in. For some reason, imapd receives
a user name of '^A' while I have entered 'stein' at the IMP login 
prompt. Of course, user '^A' does not exist, so imapd correctly
rejects. The question is: why is it receiving the '^A' and not
'stein' ??

Sessions are working just fine (I can increment the counters in the
test page).

Your help is much appreciated.
