Re: [users@httpd] mod_auth_mysql

Hi Michael!

Set your apache loglevel directive to debug. Then you can open and 

monitor your apache error log live [sudo tail -f pathToYourErrorLog] as 

you hit your protected page with your browser. You should be able to see 

what mod_auth_mysql returns to the logs.

I noticed that you are using auth_dbm_module. How is that module being used.

In my configuration, I only load the module which I need and nothing 

else. It makes troubleshooting easier [and the server a bit faster]:

LoadModule access_module modules/mod_access.so
LoadModule auth_module modules/mod_auth.so
LoadModule ldap_module modules/mod_ldap.so
LoadModule auth_ldap_module modules/mod_auth_ldap.so
LoadModule mysql_auth_module  modules/mod_auth_mysql.so
LoadModule include_module modules/mod_include.so
LoadModule deflate_module modules/mod_deflate.so
LoadModule log_config_module modules/mod_log_config.so
LoadModule env_module modules/mod_env.so
LoadModule setenvif_module modules/mod_setenvif.so
LoadModule mime_module modules/mod_mime.so
LoadModule autoindex_module modules/mod_autoindex.so
LoadModule asis_module modules/mod_asis.so
LoadModule negotiation_module modules/mod_negotiation.so
LoadModule dir_module modules/mod_dir.so
LoadModule imap_module modules/mod_imap.so
LoadModule actions_module modules/mod_actions.so
LoadModule alias_module modules/mod_alias.so
LoadModule php5_module        modules/libphp5.so

In my configuration [apache2.0.58] which I need to use dual 

authentication - mod_auth_ldap with a "failthru" to mod_auth_mysql 

[sourceforge ver 3.0] it was by trial and error that I found that  

mod_auth_mysql's load order is important. That is why I'm curious how 

you are using mod_auth_dbm.

Hello does anyone have any idea where I might look to resolve this
issue?
Many thanks.

	I'm using apache v2.0.55 and mod_auth_mysql v3 on a Gentoo Linux
box.  Below is a section from my httpd.conf - does it look right?

# These modules provide authentication and authorisation for
# clients. They should not normally be disabled.
#
LoadModule access_module                 modules/mod_access.so
LoadModule auth_module                   modules/mod_auth.so
LoadModule auth_anon_module              modules/mod_auth_anon.so
LoadModule auth_dbm_module               modules/mod_auth_dbm.so
LoadModule auth_digest_module            modules/mod_auth_digest.so

Many thanks,
Michael.

Greetings Michael!

Which versions of apache and mod_auth_mysql are you using? What platform
are you on? When you check your httpd.conf file is mod_auth being
loaded?

Hi William,
	Thanks for your help on this one.  From what you and Elaine have

written and from what I've read, this really ought to work but I'm 

still stuck with the all or nothing problem.

If I modify my file as you suggest, anyone can get access without 

being prompted for a password, not just the IP I specify; if I comment

out the 'satisfy any' line, I'm back to passwords for all.

As we agree that the approach is valid, can anyone think of any other 

commands, directives etc somewhere else that might be having an effect

on this?

Many thanks,
Michael.

Greetings Michael!

What should work is the following:

<Directory /var/www/localhost/htdocs>

deny from all
allow from 10.0.0.72

AuthName "authentication required"
AuthType Basic
AuthMySQLHost localhost
AuthMySQLEnable on
AuthMySQLUser xxxxxxx
AuthMySQLPassword xxxxxxx
AuthMySQLDB auth
AuthMySQLUserTable users
AuthMySQLNameField user_name
AuthMySQLPasswordField user_passwd
AuthMySQLGroupTable groups
AuthMySQLGroupField user_group
Require group user admin

satisfy any

</directory>

Hi Elaine,

Many thanks for the help, I've now got:

<Directory /var/www/localhost/htdocs>

AuthName "authentication required"

AuthType Basic

AuthMySQLHost localhost

AuthMySQLEnable on

AuthMySQLUser xxxxxxx

AuthMySQLPassword xxxxxxx

AuthMySQLDB auth

AuthMySQLUserTable users

AuthMySQLNameField user_name

AuthMySQLPasswordField user_passwd

AuthMySQLGroupTable groups

AuthMySQLGroupField user_group

# This next line controls which group(s) can access the resource

AllowOverride none

Require group user admin

Order allow,deny

Allow from 10.0.0.72

Satisfy Any

</Directory>

But now anyone can access it, not just the IUP address I've

specified!

I can't seem to get around this all or nothing problem.

Can you see anything I've done wrong?

Michael.

Michael,

Try to use the "allow" and "satisfy" directives.
This is an example, that we use to protect our intranet access :

(Note that the IP's and server name were modified, and we use the 

deny

directive
to refuse connections from reception kiosk.)

<Limit GET PUT POST>

# Allow access only to authenticated users from MySQL # or users that

are in the intranet # (except IP xx.xx.xx.xx : reception kiosk)

require valid-user
Order allow,deny
Deny from xxx.xxx.xx.x

# Allow access from our internal network without # username and 

password

Allow from example.com

Satisfy any
</Limit>

You can read more details about Satisfy directive :

http://httpd.apache.org/docs/2.2/mod/core.html#satisfy

Regards,
Elaine

Hi All,

I've got mod_auth_mysql working nicely but I would like the users on 

my internal network not to have to enter a username and password, 

just

people accessing from outside.

I've tried various solutions using Order deny,allow; allow from and 

so

forth but with no luck, I end up with everyone being prompted or

no-one.

Here's my unmodified <Directory> command from my httpd.conf that 

requires everyone to supply a password, can anyone suggest how I can 

modify it to allow access from 10.0.0?

<Directory /var/www/localhost/htdocs>

AuthName "authentication required"

AuthType Basic

AuthMySQLHost localhost

AuthMySQLEnable on

AuthMySQLUser xxxxxx

AuthMySQLPassword xxxxxxx

AuthMySQLDB auth

AuthMySQLUserTable users

AuthMySQLNameField user_name

AuthMySQLPasswordField user_passwd

AuthMySQLGroupTable groups

AuthMySQLGroupField user_group

# This next line controls which group(s) can access the resource

require group user admin

</Directory>
