[Kroupware] Shared Folder problems

[Errico Tin]

I'm using Kolab 1.0-1.0.12 and imapd-2.1.14-20030707_kolab.
Installed everything without any problem.
Created few accounts (A) and a shared folder.
In the share folder I created few other sub folder.
Now all accounts (A) created before I create the share + sub can see
everything and subscribe to it.
Newly created account (B) can see the shared folder but not the sub.
Any new subb folder will be available for both A and B.

What I'm doing wrong?

Thanks in advance
Regards
