AuthType Basic AuthName "Members Only" require group admin
database_name]--Tells which database you are authenticating against.
password_table_name]--Tells which table in that database contains the password information. Unless you specify, it is assumed that the username is contained in the field '
username', and the password is contained in a field '
password'. You can change this. (See below.)
group_table_name]--Ordinarily, you'll probably just want to store the group field in the same table as the usernames and passwords, but if you need to store it in a different table, this is where you'll specify where that is.
username_field_name]--If your username is a field other than '
username', you can specify that with this directive.
password_field_name]--If your password is a field other than '
password', you can specify that with this directive.
group_field_name]--If your group name is a field other than '
groups', you can specify that with this directive.
mod_auth_mysqlwhether the passwords are in the database encrypted, or plain-text. This is on by default - that is, it is assumed that your passwords are stored encrypted.
There are several other directives, but these are the main ones that you will be using most of the time. The following is an example .htaccess file that works for me:
Auth_MySQL_Info localhost db_user db_password Auth_MySQL_DB authentication Auth_Mysql_Password_Table passwordsAuthType Basic AuthName "Members Only" require valid-user
The above assumes that the username is in a field
username, and the password is encrypted, and is stored in the field
Once you have your
.htaccessfile set up as described above, you will get the password dialog as normal. There will be no difference to the user.
You can maintain your user and password lists via whatever database management tool you are used to using. There's no handy tool like
dbmmanagefor managing these accounts from the command line, but I'm working on one.
You can use Perl and DBI to talk to your database. In my next column, I'll be talking at greater length about using Perl to manage your password files. There are a plethora of ways to do this, so it really merits its own article.
mod_auth_mysqlallows you to keep your users, passwords, and groups, in a MySQL database. MySQL is a lightweight, fast, free database server which is available for most popular operating systems.
