This patch allows lighttpd to authenticate users against mySQL DBbr
NOTE: Only basic auth is implemented. Passwords are stored as MD5 hash in DB

make mysql db and user (read mySQL doc's if you don't know how)
import lighttpd-1.4.11-mysql_auth.sql

open lighttpd.conf and add
(be sure that you comment out any other auth - according to lighttpd docs)

auth.backend                                   = "mysql" 
auth.backend.mysql.host                        = "localhost" 
auth.backend.mysql.user                        = "db_user" 
auth.backend.mysql.pass                        = "db_pass" 
auth.backend.mysql.db                          = "db_name" 
auth.backend.mysql.port                        = "0" # (for default port 0, always needed)
auth.backend.mysql.socket                      = ""  # (for default leave blank, always needed)
auth.backend.mysql.users_table                 = "users_table" 
auth.backend.mysql.col_user                    = "col_name_username" 
auth.backend.mysql.col_pass                    = "col_name_password" # (md5 hash of password)
auth.backend.mysql.col_realm                   = "col_realm_name" 

configure lighttpd to use it (same as every other auth)

auth.require = ( "/some_path" =>
    (
        "method"  => "basic",
        "realm"   => "some_realm",
        "require" => "some_user",
    )
)

start lighttpd

P.S. patch include more complicated setup with separate table for domains.
