I don't think this is a wise idea. LDAP does not like to be written to.

With approach like you envision you will certainly kill your LDAP server
instantly. If you have any replicated slaves, the write load you will be
creating will kill them a second later.

Either use post-login scripting to store that value in a SQL database,
or better, just touch a file in the users $HOME.

Question: why do you need this las-login timestamp information? Maybe
there is a better way to solve your problem/need.
