Ivan has created such a generic microservice ( the attribute processor [0] ) that can be used to implement and define small attribute processing filters. See for example [1] that contains a number of examples of such processors ( attribute hashing, extracting scopes, etc. ) An example on how to change an attribute value via the attribute_processor microservice and the relevant processors can be found in [2] [0] https://github.com/SUNET/SATOSA/blob/master/src/satosa/micro_services/attri… [1] https://github.com/SUNET/SATOSA/tree/master/src/satosa/micro_services/proce… [2] https://github.com/SUNET/SATOSA/blob/master/example/plugins/microservices/a… On 17/09/2017 09:48 μμ, Rainer Hoerbe wrote: -- ------------------------------------------------------------------ Ioannis Kakavas - ikakavas at grnet.gr Identity and Security Engineer GRNET Network Operations Centre Greek Research & Technology Network - http://www.grnet.gr 7, Kifisias Av. 115 23 Athens, Greece Office: +30 2107474255 PGP Fingerprint: A5AA FB5E 740A 603B FAB1 9920 D70F 0CD5 9DE3 C262 ------------------------------------------------------------------
