ConfigurationFileSummary

The configuration file count is very large, partly due to supporting so many features, partly because we have created smaller units of configuration dealing with specific tasks, and partly because we've tried to expose a lot of options directly without requiring code changes or plugins. In practice, you should expect to interact with the same files as in earlier versions on a regular basis and you may never touch many of these files.

To help orient you, a summary of the general function of each file follows along with a tip for when or why you might care about it. The order is alphabetic, not based on the frequency of use.

Many other files may optionally exist, but are only installed when particular modules are enabled and will be described in the relevant topics.

The "RL?" column notes which files can be reloadable, but not necessarily which ones are since that depends on the "checkInterval" properties in services.properties.

File	RL?	Purpose	Tasks

File	RL?	Purpose	Tasks

global.xml	N	A place to put globally visible custom Spring bean definitions, empty by default	Override built-in behavior of low-level components such as storage or session management Create utility bean definitions to help define other custom beans located elsewhere Override built-in global algorithm blacklist
idp.properties	N	Java property file used to change common or important settings more easily	Set important global settings like the unique entityID of the IdP, the attribute qualifying scope/domain, pathnames and passwords for keys Change lots of globally significant settings
ldap.properties	N	Java property file with LDAP authentication and attribute lookup settings	Configure general LDAP location, credentials, and search properties Use separate directories for authentication and attribute lookup
logback.xml	Y	Logback logging configuration	Change unusual logging levels, locations, file retention behavior Add custom log destinations (e.g., syslog)
metadata-providers.xml	Y	Configure sources of SAML metadata	Add metadata sources Control metadata verification and filtering
mvc-beans.xml	N	A place to put custom bean definitions for the Spring MVC layer, not created by default	Mostly just for extension authors if they need to make changes or additions like adding MVC controllers or adding new view technologies
relying-party.xml	Y	Controls which profiles are enabled for which relying parties and the profile settings used with them	Turn profiles on and off Customize profile features like signing and encryption, attribute push/pull Set preferred authentication types based on RP or profile Turn special intercept flows on and off (e.g. attribute consent, usage terms, permission checks) Enable "open" operation without requiring metadata for SPs
saml-nameid.properties	N	Java property file with settings controlling SAML NameID generation and consumption	Toggle between stateless and in-memory transient identifiers Toggle between hash-generated and database-backed persistent/pairwise identifiers Change default NameID formats
saml-nameid.xml	Y	Controls support for and generation/sourcing of SAML NameIDs	Turn on or off transient and persistent identifier support Configure custom NameIDs based on resolved attributes
credentials/secrets.properties	N	Parking lot for any properties of a secret nature that should not be checked into configuration management tools	Setting various passwords present in a default install Adding additional passwords in the future
services.properties	N	Java property file with pointers to the resource collections that configure important services and settings controlling configuration reload policy	Customize the reloadability of various service configurations Control fail-fast behavior at startup Override the resources that configure services without editing services.xml
services.xml	N	Controls the resources loaded to configure important services, and allows for advanced resource types such as subversion	Add or change resources loaded to configure metadata, relying party settings, attribute resolution and filtering, and other services Add Spring configuration in support of advanced resources like Subversion files or HTTP resource requirements such as TLS certificate checking
admin/admin.properties	N	Customization of administrative flows (replaces most of the need for general-admin.xml in previous versions)	Customize flow settings such as authentication or access control rules
admin/metrics.xml	N	Configures customizable instrumentation and reporting features	Enable or disable metrics Configure metric reporting features Enable customized timers or counters
attributes/default-rules.xml (and various schema-specific rule files)	Y	Default mapping rules for "conventional" attributes in common or standard usage	Change default mappings Add or update language translations
attributes/custom/	N	A directory in which property-based attribute mapping rules can be dropped for local customization	Add your own attribute mapping rules using property syntax
authn/authn-comparison.xml	N	Establish relationships between authentication methods in terms of protocol-specific identifiers such as SAML AuthnContext classes	Support non-exact matching between requested and supported authentication methods, such as indicating that a multi-factor method is "better than" a password Map SAML AuthnContext values while proxying
authn/authn-events-flow.xml	N	A webflow definition file for enumerating custom events to use as the result of custom authentication flows	Support a custom Event as the result of an authentication flow for error handling purposes or as flow control within the MFA feature
authn/authn.properties	N	Customization of authentication flows (replaces most of the need for general-authn.xml and many of the other authn-related XML files in previous versions)	Customize authn settings such as timeouts, and support for SAML AuthnContext classes for controlling login method selection
c14n/subject-c14n-events-flow.xml	N	A webflow definition file for enumerating custom events to use as the result of custom canonicalization flows	Support a custom Event as the result of a canonicalization flow for error handling purposes
