Enable SAML authentication

Identity Provider Settings

The Identity Provider (IdP) must be set up to provide the property Redirect URIs on successful logins to https://host:port/saml/SSO

The IdP can provide a logout URL redirection to https://host:port/saml/SLO

See SAML authentication - Set up IdP for use with RapidMiner for more details.

Changing SAML settings

By default, SAML authentication for RapidMiner Server is disabled. If you want to enable it, you need to modify the property file local-security.properties, located in the in the /configuration subfolder of your RapidMiner Server home directory, and restart RapidMiner Server.

#
# Properties for using SAML authentication with RapidMiner Server
#
# Quick SAML abbreviations:
# - IdP - Identity Provider. It is a 3rd party application responsible for the authentication
# - SP - Service Provider. Any application which uses the IdP to authenticate a user which tries to
#                          access a resource protected by this service. 
#              In this context RapidMiner Server is an SP
#

#
# Authentication source defines fundamental behaviour of RapidMiner Server
# It decides authentication experience and the identity source 
# (primary source of checking the user credentials and organisational group membership information)
#
# DB          - Unauthenticated user will be displayed a form based login and DB or direct LDAP connection
#               will act as an the identity store
# SAML        - Unauthenticated user will be immediately displayed an login screen of an IdP
#               (to which RapidMiner server is registered to) and
#               solely the IdP is responsible to act as an the identity store
# DB_AND_SAML - Mixed mode. Unauthenticated user will be displayed a form based login where he 
#       has the option to choose between DB/LDAP or SAML experience. This mode is for experimenting 
#       with SAML configuration and helping the transition from DB/LDAP to SAML mode. 
#       It is not recommended to use this mode in production
#
# Default value is 'DB' to preserve backward compatibility with versions prior to 9.3.0
#
rmserver.authentication.source=SAML

#
# Authentication strategy used to fetch the information details of a logged in user
# useLocalProfile - Existing user accounts are going to be mapped by user email addresses so need to 
#           have a user established RapidMiner Server first (with the correct the email address) 
#           to allow access.  The user account on RapidMiner server needs to also have correct 
#           permission/group established. This is a 'read only' setup thus new users will not be 
#           created in RapidMiner Server upon login but rather access will be denied. 
#           (Default setting)
#
# syncOnLogon     - Mirror user locally by syncing there personal details (user unique id, displayable user
#           name, email address and organisational group membership) from IdP after successful login.
#                   Details of the user is fetched solely from the SAML response message and only during login.
#                   New users are created upon first successful login. With their privileges either mirrored 
#           based on predefined organisational group <-> privileges mappings or static privileges 
#           setup 
#           (for RapidMiner Server groups which have enabled the setting of all new user membership)
