IdP files/directories permissions "reset"

[Youssef GHORBAL]

Hello,

	I've somehow butchered permissions/ownerships of an IdP installation directory (/opt/shibboleth-idp)
	Is there a refrence somewhere I can check to reset to the expected/default permissions of files/dirs. Like "credentials/*" is supposed to be chmod xxx (same question for files ownership regarding the usage of a "jetty" user/group that will run the service)
	
	Thank you for your help!
