simple ACL requirement, grant access to modify myself and my sub entries, not sure how to do it

Dear all. In my installation it's required if someone logs in, he can modify his own entry and can modify & delete & create entries of his own entry, e.g.

login as: dn: ou=Support,o=Real Softservice

Then I should be able to modify & delete & create:

dn: cn=Wang Penghui,ou=Suport,o=Real Softservice

dn: cn=Zhang Weiwu,ou=Suport,o=Real Softservice

dn: cn=Wolfgang Scheuing,ou=Suport,o=Real Softservice

Looks like a simple requirement. Anyway I dug into ACL manual for days without a clue (maybe also because of my bad English). Can anyone provide a hint and simplified example? Thanks a lot in advance!
