subtree write access

["Evgeny O. Oleynikov" <evg@atom.krasnet.ru>]

Hi,
the directory consists of such records:
ou=A
| \uid=A1, ou=A
|...
\ou=AA, ou=A
| \uid=AA1, ou=AA, ou=A
....
ou=B
...
It is necessary for me to write ACL so that each user had the right to 
write in all groups, nested in group of this user.
For example:
uid=A1, ou=A
should have the right to writing in "ou=AA, ou=A ", " ou=AAA, ou=AA, 
ou=A" etc.
uid=BBB1, ou=BBB, ou=BB, ou=B
should have the right to writing in "ou=BBBB, ou=BBB, ou=BB, ou=B" etc.
How to me it to make?

Regards
