[Q] how to refresh Dynamic Directory Services object ttl?

greetings,

how can I refresh ttl of Dynamic Directory Services object with 
Net::LDAP?

for OpenLDAP there is overlay dds (described in 12.5 section of 
http://www.openldap.org/doc/admin24/overlays.html)

so, how can I do something like this:

ldapexop -x -H ldap://ldaphost "refresh" 
"[email protected],[email protected],uid=naf.naf,ou=People,dc=umidb" 
"10d" -D "uid=admin,ou=People,dc=umidb" -W

is it, just modifying attr `entryTtl'?
