Dear all We have accesslog feature turned on for several months. It's very useful for us to identify who have modified what (only edit access is logged). The new requirement is to search for all entries that have modified themselves; I don't know how to do (and failed after many experiments). It's very easy to identify whether or not a given user have modified herself by doing: ldapsearch ... '(&(reqDN=uid=zhangweiwu,ou=contacts,dc=eoa,dc=cn)(reqAuthzID=uid=zhangweiwu,ou=contacts,dc=eoa,dc=cn))' But I need to do this search 4000 times to locate all entries who have modified themselves. I wish I can work smarter using something like ldapsearch ... '(&(reqDN=\(.*\))(reqAuthzID=\1))' Certainly this doesn't work but you get the idea. Is there a solution? Thanks a lot in advance! Would you please kindly use "reply all" to reply this message so that my colleague on the 'cc' can be enlightened too? -- Zhang Weiwu Real Softservice http://www.realss.com +86 592 2091112
