IMP Login failures

[Gautam Das]

System is Redhat 7.1, horde-1.2.6, IMP - 2.2.6,	Cyrus - 2.0.16,	Apache -
1.3.19-5, openssl-0.9.6-3, mysql-3.23.36-1

Test user gumby  can login and read mail with pine. Cyrus Imapd uses
sasldb.

imapd.log shows success

Oct 19 13:12:01 email2 imapd[15235]: login: redhat[127.0.0.1] gumby
CRAM-MD5 User logged in
Oct 19 13:12:01 email2 imapd[15235]: seen_db: user gumby opened
/var/imap/user/g/gumby.seen
Oct 19 13:12:01 email2 imapd[15235]: open: user gumby opened INBOX

However gumby cannot login with IMP. Here is the error logged by IMP

IMP[14524]: FAILED 192.168.0.102 to email2.bic.org:143 as gumby

In apache access.log I see
"GET /horde/imp/login.php3?reason=timeout"

In apache error.log I see
Login failed: authentication failure (errflg=1) in
<b>/var/www/html/horde/lib/horde.lib<

It appears a login request never gets to Cyrus, because I don't see
anything logged in imapd.log.

What am I missing?
