Code Block
# to provide custom authentication (instead of the default httpServletRequest.getUserPrincipal()
# for non-Rampart authentication.  Class must implement the interface:
# edu.internet2.middleware.grouper.ws.security.WsCustomAuthentication
# class must be fully qualified.  e.g. edu.school.whatever.MyAuthenticator
# blank means use default: edu.internet2.middleware.grouper.ws.security.WsGrouperDefaultAuthentication
ws.security.non-rampart.authentication.class = edu.internet2.middleware.grouper.ws.security.WsGrouperKerberosAuthentication

################# KERBEROS settings, only needed if doing kerberos simple auth ################
# realm, whatever your realm is, e.g. SCHOOL.EDU
kerberos.realm = SCHOOL.EDU
# address of your kdc, e.g. kdc.school.edu
kerberos.kdc.address = kdc.school.edu
