ACLs based on attributes?

[Jaap Winius <jwinius@umrk.nl>]

Hi all,

Is it possible to define an ACL that gives a DN access to a particular  
attribute in other DNs based on the value of one of its own attributes?

For example, would it be possible to define an ACL that would allow a  
DN with title=telephonemanager to update only the telephoneNumber  
attribute of other DNs? In other words, the ACL would allow updates to  
telephoneNumber, but only for search filter title=telephonemanager; a  
simple a change of the title would result in the gain or loss of the  
right to make such updates.

Thanks,

Jaap
