Hi All,
I am having an existing project where form based login is implemented. It has database table and login.jsp. I tried to figure out how j_security_check is linked to the database for pulling user out and validating.
i got login-config.xml file in my
JBoss server. It has following.
- <application-policy name="ioclpower_domain">
- <!--
A simple server login module, which can be used when the number
of users is relatively small. It uses two properties files:
users.properties, which holds users (key) and their password (value).
roles.properties, which holds users (key) and a comma-separated list of
their roles (value).
The unauthenticatedIdentity property defines the name of the principal
that will be used when a null username and password are presented as is
the case for an unuathenticated web client or MDB. If you want to
allow such users to be authenticated add the property, e.g.,
unauthenticatedIdentity="nobody"

- <login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required">
<module-option name="dsJndiName">

<module-option name="principalsQuery">Select USERPASS from UM_USERS_FORJAAS where USERID = ?</module-option>
<module-option name="rolesQuery">Select SYSROLE 'Roles', USERROLEGROUPS 'RoleGroups' from UM_USERSYSROLES_FORJAAS where USERID = ?</module-option>
<module-option name="hashAlgorithm">MD5</module-option>
<module-option name="hashEncoding">base64</module-option>
</login-module>
</authentication>
- <!--
<authentication>
<login-module code = "org.jboss.security.auth.spi.UsersRolesLoginModule"
flag = "required" >
<module-option name="usersProperties">iocl.users</module-option>
<module-option name="rolesProperties">iocl.roles</module-option>
</login-module>
</authentication>
-->
</application-policy>
can anybody explain about above thing?
where is it checking the password? is there any standard for database table names and field names?
thanks in advance.
