[imp] some imp/config/pref.php settings ignored for some accounts

[amy.rich@tufts.edu]

We're running imp 4.0.4, horde 3.0.5.

We have two types of accounts, person and group.  We authenticate both using
IMP (IMAP) authentication.  We have hooks (horde/conf/hooks.php) into LDAP
that set from_addr and full_name (which are defined differently if one is a
group account or a person account).

The imp/confg/prefs.php settings in question are:

$_prefs['sent_mail_folder'] = array(
    'value' => 'Sent',
    'locked' => false,
    'shared' => false,
    'type' => 'implicit');

$_prefs['spam_folder'] = array(
    'value' => 'Junk',
    'locked' => false,
    'shared' => false,
    'type' => 'implicit');

These default folders show up correctly for real users, but not for group
users.  For group users, the Spam folder value is set to "None" instead of
"Junk" under: Options -> Options for Mail -> Server and Folder Information.

Both group and person accounts have "Sent mail folder" set to "Use Default
Value" under: Options -> Options for Mail -> Personal Information.  When a
group user click on Compose, though, the sent folder shows up as "sent-mail"
instead of the "Sent" that a person account sees.  

There are no errors logged, so I'm stumped.  I'm not sure why horde/imp would
be treating these two types of accounts differently, since they're both just
plain old imap.  My only thought is that it might be something in LDAP.
Anyone have any ideas?  Here are two types of LDAP entries:


Here's a group entry:

And here's a person entry:
