1. Preface.

This PATCH allows to assign many PC's with one IP but differing in MACs 
to one person. Changes are only in database and user interface.

2. Installation.

Copy patch to LMS's dir and type:

$ patch -p1 <multiip-patch.diff

Next you should delete unique key in database: 

$ mysql -u lms -D lms -e "ALTER TABLE nodes DROP INDEX ipaddr"
$ psql -U lms -d lms -c "ALTER TABLE nodes DROP CONSTRAINT nodes_ipaddr_key"

For speed up some DB-related work you could add index on IP address:

$ mysql -u lms -D lms -e "ALTER TABLE nodes ADD INDEX ipaddr(ipaddr)"
$ psql -U lms -d lms -c "CREATE INDEX nodes_ipaddr_idx ON nodes(ipaddr)"
