Manually configuring SAML authentication

To manually configure Data Explorer for SAML authentication on unmanaged clusters, you must add GCC Python libraries and install xmlsec1 tools on all the hosts in your cluster.

These instructions assume that you have an Identity Provider set up and running. You can use any identity provider of your choice. For example, Okta, Ping Identity, and OpenAM.

  1. Install the following libraries on all hosts in your cluster: 
    ## RHEL/CentOS
yum install git gcc python-devel swig openssl
    ## Ubuntu/Debian
apt-get install git gcc python-dev swig openssl
    ## SLES
zypper install git gcc python-devel swig openssl make libxslt-devel libltdl-devel
  2. Install xmlsec1 and xmlsec1-openssl on all hosts in the cluster: 
    ## RHEL/CentOS 
yum install xmlsec1 xmlsec1-openssl
    ## Ubuntu/Debian
apt-get install xmlsec1 libxmlsec1-openssl
    ## SLES (get latest version)
wget http://www.aleksey.com/xmlsec/download/xmlsec1-1.2.24.tar.gz
tar -xvzf xmlsec1-1.2.24.tar.gz
cd xmlsec1-1.2.24
./configure && make
make install
  3. Copy metadata from your identity provider's SAML server and save it as an XML file on every host with a Hue server. For example, if your identity provider is Shibboleth, visit https://<idp_host>:8443/idp/shibboleth, copy the metadata content, and paste it into an XML file. Read the documentation of your identity provider for details on how to copy the XML of the SAML server metadata. 
    mkdir -pm 755 /opt/cloudera/security/saml/
cd /opt/cloudera/security/saml/
    vim idp-<your idp provider>-metadata.xml
# Paste IdP SAML here and save
  4. Add the files that the key_file and cert_file SAML properties point to for encrypted assertions and make sure you add this properties to the hue.ini configuration file.
    • The key_file parameter points to the location of the private key that is used to encrypt metadata. Its file format must be <file_name>.PEM.
    • The cert_file parameter points to the location of the X.509 certificate that is sent with encrypted metadata. Its file format must be <file_name>.PEM.
