allow a user create some objects under his entry

[François Beretti <francois.beretti@enatel.com>]

Hi,

Just in case it would help somebody, here are my acl rules to allow a 
user to create entries of a given objectClass under himself :

access to attrs="children" by self write

access to filter="objectclass=myGivenObjectClass" 
dn.regex="([^,]+)=([^,]+),([^,]+)=([^,]+),.*"
       by dn.regex="$3=$4,$5" write

So any authentified user can create entries of class 
'myGivenObjectClass' just under its entry.
Since I don't use 'cn' or 'uid' in it, this acl works even if the 
attribute used for the RDN is modified, for example if you use 
cn=francois,ou=... to name the users, or uid=francois,ou=...

It seems to work, tell me if you see a mistake or a possible improvement.

François
