As always, no clue.

In ldap (atleast with openldap) you can use lastmod on | off
here is the excerpt from slapd.conf manpage

lastmod on | off
Controls  whether slapd will automatically maintain
the modifiersName,  modifyTimestamp,  creatorsName,
and  createTimestamp  attributes  for  entries.  By
default, lastmod is off. 

you can then use this attribute to sort the result.
ldapsearch -S modifytimestamp var=val
