Configure Apache Knox authentication for PAM

Knox authentication configurations for PAM in Cloudera Manager. PAM is the default SSO authentication provider in CDP Private Cloud.

note

The knox user needs permission on /etc/shadow for PAM authentication. Allow the knox user to read the /etc/shadow file:

groupadd shadow
usermod -a -G shadow knox
chgrp shadow /etc/shadow
chmod g+r /etc/shadow

SSO authentication for PAM

In CDP Private Cloud, Cloudera Manager added a new Knox configuration, called

Knox
          Simplified Topology Management - SSO Authentication Provider

, with the following initial configuration:

role=authentication
authentication.name=ShiroProvider
authentication.param.sessionTimeout=30
authentication.param.redirectToUrl=/${GATEWAY_PATH}/knoxsso/knoxauth/login.html
authentication.param.restrictedCookies=rememberme,WWW-Authenticate
authentication.param.urls./**=authcBasic
authentication.param.main.pamRealm=org.apache.knox.gateway.shirorealm.KnoxPamRealm
authentication.param.main.pamRealm.service=login

Every change here is applied to the knoxsso topology that affects manager, homepage and cdp-proxy topologies as they are using the federation provider.
