Missing in 1.5.x:


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

br" class="external">lighttpd-1.4.11-mysql_auth.patch</a>

tar xzvf lighttpd-1.4.11.tar.gz     # (unpack source)
patch -p0 < lighttpd-1.4.11-mysql_auth.patch     # (apply patch)
cd lighttpd-1.4.11
./configure --with-mysql     # (add more options if you want)
make install

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

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

auth.backend                                   = "mysql"                        = "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

test & Njoy

Is there a patch to the current version 1.4.18? I tried it myself to merge the 1.4.11-patch to this version, but it didn't work...

This patch work fine for me> johann.

But i think this patch has SQL Injection probrem.
i think it should use mysql_real_escape_string().
such as attached file.

but i think this version still has a probrem.
i think all of MySQL related lines should be in #ifdef HAVE_MYSQL ... #endif.
Sorry i could not resolve this probrem.
i read ldap related lines. i think there are many ldap line at outside ifdef. i can't understand it. sorry.

If i got my lighty running with mysql-auth, ill try to add mysql_real_escape_string() but C is not even rudimental my preferred language :)

Best regards,

Sorry, for the late response:

I tried the latest patch, but it doesnt worked for me. Patching and build was fine, but on restart after configuration, i got:

2008-03-21 14:27:37: (plugin.c.165) dlopen() failed for: /usr/lib/lighttpd/ /usr/lib/lighttpd/ undefined symbol: mysql_query 
2008-03-21 14:27:37: (server.c.621) loading plugins finally failed                                                                                                          

The System is a Gentoo Linux with mysql installed and mysql-support in lighttpd.
Sorry, but atm i have no time to dig deeper...

Looks like the module is not linked against mysql; so you either need to fix the or load the mysql-vhost module before mod_auth so mysql is already loaded

#7 Updated by Anonymous about 8 years ago

DrJeckyll's latest patch made my 1.4.19 segfault, so I've here's my version, based on the one by Taguchi.

I've also added support for digest authentication, in which the 'password' field should look like this:


This is easy to use when you create a MySQL view:

SELECT username AS username, MD5(CONCAT(username,':',realm,':',password)) AS password, realm AS realm
FROM auth

  • Target version set to 1.4.x

Compiling the 1.4.28 patch against the current lighty version (1.4.31) doesn't seem to work.

1.4.28 - works! (tested)
1.4.29 - works! (tested)
1.4.30 - breaks compile (tested)
1.4.31 - breaks compile (tested)

http_auth.c: In function 'http_auth_basic_password_compare':
http_auth.c:987:24: error: 'MD5_CTX' undeclared (first use in this function)
http_auth.c:987:24: note: each undeclared identifier is reported only once for each function it appears in
http_auth.c:987:32: error: expected ';' before 'Md5Ctx'
http_auth.c:991:24: warning: implicit declaration of function 'MD5_Init'

http_auth.c:992:24: warning: implicit declaration of function 'MD5_Update'
http_auth.c:993:24: warning: implicit declaration of function 'MD5_Final'

Taking a look at the changelog, I've spotted this:

[mod_auth] Fix signedness error in http_auth (CVE-2011-4362)

Any1 want to take a shot at writing a patch for 1.4.x ?
