As far as I am aware, there is no attribute in the OpenLDAP shema that holds the last logon (or last bind) time or built-in slapd functionality to do so. If I am incorrect, please let me know.
If I am correct, I am wondering if there is any way to implement triggers that can be executed when a successful bind operation happens such as executing a shell script that will modify a user-defined attribute that holds a timestamp.
Thanks much,
