JDBCLoginModule
Authenticate Users with Jetty JAAS JDBCLoginModule
Configure kPow to read authentication and role information from a database via JDBC.
Form or Basic Authentication?
kPow supports both form-based and basic authentication.
Form authentication is the default. To basic authentication, set the environment variable:
1
JETTY_AUTH_METHOD=basic
Copied!
Configuration
To enable LdapLoginModule authentication you must:
- Create a JAAS configuration file
- Set the
AUTH_PROVIDER_TYPE=jettyenvironment variable. - Start the JAR or Docker container with
-Djava.security.auth.login.config=/path/to/jaas.conf
JAAS Configuration
Create a JAAS JDBC configuration file (the kpow realm is very important).
1
kpow {
2
org.eclipse.jetty.jaas.spi.JDBCLoginModule required
3
dbUrl="jdbc:hsqldb:."
4
dbUserName="sa"
5
dbDriver="org.hsqldb.jdbcDriver"
6
userTable="myusers"
7
userField="myuser"
8
credentialField="mypassword"
9
userRoleTable="myuserroles"
10
userRoleUserField="myuser"
11
userRoleRoleField="myrole";
12
};
Copied!
Environment Configuration
To activate Jetty JAAS authentication set the environment variable
AUTH_PROVIDER_TYPE=jettyJAR Startup
Specify the JAAS config file by setting the following system property when starting the JAR:
-Djava.security.auth.login.config=/path/to/jaas.conf Note: System properties must come after java but before -jar.
1
AUTH_PROVIDER_TYPE=jetty \
2
<... more env vars ...> \
3
java -Djava.security.auth.login.config=/opt/kpow/jaas.conf -jar /opt/kpow/latest.jar
Copied!
Docker Container Startup
Note: The JVM provides an environment variable called
JAVA_TOOL_OPTIONS that can be used in place of system properties. We use this the thread the JAAS config to Docker.Set the env var
JAVA_TOOL_OPTIONS=-Djava.security.auth.login.config=/path/to/jaas.confNote: When your JAAS config is on the host machine and not within the container you will need to configure a docker volume mount so that kPow can read that configuration:
docker run --volume="/config/path:/config/path/" -p 3000:3000 --env-file ...When starting the docker container you will see logging output similar to:
1
Picked up JAVA_TOOL_OPTIONS: -Djava.security.auth.login.config=/path/to/jaas.conf
Copied!
User Experience
When configured your users will be prompted to authenticate on each new browser session.
