I set up remote LDAP server (Server1) and SSH with pam\_ldap on Server2. Everything is working ok, I can login to SSH with LDAP credentials. But when I want to add new user, I have to firstly create it in LDAP databases and then run adduser on Server2.

How can I automatically create the user account on Server2 after adding it to LDAP database ? For example when the user first logs in? Thanks.
