Toltec connector duplicates appointment attendees

[Albrecht Dreß]

Hi all,

while evaluating the Toltec connector and Toltec LDAP address book for  
Outlook I found a puzzling behaviour...

I created two users "Test 1 Benutzer" and "Test 2 Benutzer", both  
accepting invitations automatically.  Invitations are sent from "Test 1  
Benutzer" to "Test 2 Benutzer", taking the latter from the LDAP address  
book.

If I configure the LDAP address book to show names as "First Last",  
everything works fine.  However, setting it to display names as "Last,  
First" (which results in "Benutzer, Test 2" for the example above), the  
"accept" message will create a /second/ user in the appointment object  
in IMAP:

   <attendee>
     <display-name>Benutzer, Test 2</display-name>
     <smtp-address>test2 at my-company.com</smtp-address>
     <status>none</status>
     <request-response>true</request-response>
     <role>required</role>
   </attendee>
   <attendee>
     <display-name>Test 2 Benutzer</display-name>
     <smtp-address>test2 at my-company.com</smtp-address>
     <status>accepted</status>
     <request-response>true</request-response>
     <role>optional</role>
   </attendee>

The first entry was the original one, and the second has been added.  I  
checked the vcalendar message produced automatically, and it contains  
only "ATTENDEE;PARTSTAT=ACCEPTED:MAILTO:test2 at my-company.com".

I'm not sure whether Toltec or Outlook or Kolab is the source of the  
bug, but it is somewhat annoying...  Any idea how it could be fixed?

Thanks, Albrecht.
