GeoServer OAuth 2.0

Is anyone out there using OAuth to authenticate GeoServer users? I've been through installing and configuring this extension. I've tried Google and GitHub providers. I end up with a 404 error trying to access the login page. Same issue as here. There are no errors in the log with the debug level elevated as suggested.

Solution

Answering my own question here...

For me the 404 problem solved by building from source and accounting for the required dependencies using a maven plugin. Previously, I was attempting to use the prebuilt binaries and lib/ depedencies.

I built the modules from source (2.18.3) and modified the file maven file to copy the dependencies to the target folder, which I then copied to WEB-INF/lib.

Here is the pom file addition I made to get the dependencies.

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>2.8</version>
        <executions>
          <execution>
            <id>copy-dependencies</id>
            <phase>prepare-package</phase>
            <goals>
              <goal>copy-dependencies</goal>
            </goals>
            <configuration>
              <outputDirectory>${project.build.directory}/classes/lib</outputDirectory>
              <includeScope>runtime</includeScope>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
