[kronolith] Not able to share calender with specific individual users.

[Anant Athavale]

Dear List:

I am using HORDE 3.1.1 and all other stable releases of this branch  
including kronolith.

I use Cyrus-IMAP for user folders.

When I Edit permission for my calender, I get

Owner Permissions:

asa at isac.gov.in  Show Read Edit Delete

In case of Individual Users:

The list contains usernames without domain.

and this may be the reason for not able to share my calender with  
specific users.

How do I address/solve this problem?

Regards,

Anant.
