How to Track User Last Login Date and IP Address

=================================================

WARNING

Tracking operation MAY cause PERFORMANCE ISSUE on a BUSY server
due to frequently update the SQL database/LDAP directory server, AND
roundcube webmail will automatic check users' mailbox via IMAP protocol
frequently.

Requirements

This tutorial is written for Dovecot-1.x. If you have Dovecot-2.x running, please refer to official tutorial.

Modify dovecot.conf, add 'mail_executable' in protocol imap and/or pop3

    protocol imap {
        mail_drop_priv_before_exec=yes
        mail_executable = /usr/bin/trackLastLogin.sh imap
        ...
    }

    protocol pop3 {
        mail_drop_priv_before_exec=yes
        mail_executable = /usr/bin/trackLastLogin.sh pop3
        ...
    }

Download samples/trackLastLogin.sh, copy to /usr/bin/trackLastLogin.sh, set correct owner and permission.

# wget http://iredmail.googlecode.com/hg/extra/trackLastLogin.sh
# mv -i trackLastLogin.sh /usr/bin/
# chown root:root /usr/bin/trackLastLogin.sh
# chmod 0755 /usr/bin/trackLastLogin.sh

Open /usr/bin/trackLastLogin.sh, choose your preferred update method.

Currently, it supports updating user last login data to plain text, MySQL database and OpenLDAP directory server.

• For plain text, user 'dovecot' must have write privilege on the log file.

• For MySQL database, you must specify correct mysql user and password, this mysql user should have SELECT and UPDATE privilege.

• For LDAP server, you must specify correct URI, bind dn and password, this bind dn should have write privilege.
