OK, I inadvertently posted a comment meant for an enhancement to be posted tomorrow, so here we go with tomorrows enhancement of the day:
Talking once more about delegation... There's quite a big fly in the ointment we need to talk about:
While delegation granting dialogues in OBEO and bcentral take care of permissions for default folders like inbox, sent items, drafts etc. and pseudo folders like calendar or contacts, it does not so for non-default folders.
We have the case of a superior that has a widely ramified folder structure and granted his secretary access to parts of it. When the secretary changed he changed delegation, and this did not change the non-default acls.
So far nothing unspectacular. The issue is, that there is no option in OBEO to define permissions tree-wise (nor is there in beectl), so the superior had to walk the whole directory hierarchy to adapt the permissions, each folder requiring multiple clicks.
There was a permissions dialogue for that in OBEO 1.5, but has been dropped.
There is an enhancement request I'd ask you to second through MOS:
10065126: READD THE SUB FOLDER SHARING OPTION TO OBEO
This ER had the status approved for future release, but product management changed its plans and put it to "Suggestion Rejected".
a related ER is the following:
12557969: OBEO PERMISSIONS DIALOGUE SHOULD HAVE A TREE OPTION
"The Beehive platform is designed from the ground up to be easy to manage." (cited from "Oracle Beehive: A Flexible Collaboration Platform for the Enterprise") - let's hope product management will give us tree perms management, at least in OBEO.
