You can use the subject of the certificate in an ACL or in a group, for 

dn: cn=administrators, dc=rentec,dc=com
objectClass: top
objectClass: groupofNames
member: uid=/C=US/ST=New York/L=East Setauket/O=Renaissance Technologies Corp.
 /CN=Karsten Kuenne/Email=kuenne@rentec.com
member: ....
member: ....
cn: administrators

It'll probably become much more useful with 2.1 but you can start already
