[imp] IMP LDAP warnings

[Per Bothner]

I've got IMP working, but I'm getting some troubling warnings.
After I log in to IMP 3.1, I get these messages:

Warning: LDAP: Unable to perform the search: No such object in 
/var/www/html/horde/lib/Prefs/ldap.php on line 292

Warning: LDAP: modify operation could not be completed. in 
/var/www/html/horde/lib/Prefs/ldap.php on line 415

Warning: Cannot add header information - headers already sent by (output 
started at /var/www/html/horde/lib/Prefs/ldap.php:292) in 
/var/www/html/horde/imp/redirect.php on line 84

My horde/config/horde.php cpntains the following.  This is my
guess, since the documentation does not tell me what to do:
$conf['prefs']['driver'] = 'ldap';
$conf['prefs']['params']['hostspec'] = 'bothner.com';
$conf['prefs']['params']['port'] = '389';
$conf['prefs']['params']['basedn'] = 'dc=bothner,dc=com';
$conf['prefs']['params']['uid'] = 'mail';


Also, when I try the IMP test page I get the following, which I
assume is unrelated:

IMP Version

     * IMP: 3.1

PHP Version

     * View phpinfo() screen
     * PHP Version: 4.1.2
     * PHP Major Version: 4.1

* You are running a supported version of PHP.

INBOX has messages ( new recent)

Any ideas?
