It's very easy to use post-login-scripting as described on

http://wiki2.dovecot.org/PostLoginScripting

You just have to code the LDAP-updates in bash.

But: We have done this in the past, but we realized, that those many
user-logins (~15.000 to ~20.000 active users simultaneously) had been a
measureable impact on our LDAP. Okay, not very suprising...

We decided to use the simple way of touching ~/.lastlogin.

It should be easy to set up a second script that updates the
LDAP-records once per night. Normally there shouldn't been a reason to
have lastlogin updated "realtime" in LDAP many time per hour.
