Incorrect username is passed to principal when principal-transformers are enabled --------------------------------------------------------------------------------- Key: ELY-913 URL: https://issues.jboss.org/browse/ELY-913 Project: WildFly Elytron Issue Type: Bug Affects Versions: 1.1.0.Beta21 Reporter: Ondrej Lukas Assignee: Darran Lofthouse Priority: Critical In case when some principal-transformers are used for transforming principal in security domain then final username which is used for authentication and later for authorization is: input_username transformed by pre-realm-principal-transformer, post-realm-principal-transformer and realm principal-transformer. However Principal assigned to SecurityIdentity uses only name input_username transformed by pre-realm-principal-transformer. It seems it is caused by passing {{preRealmPrincipal}} as fourth parameter in https://github.com/wildfly-security/wildfly-elytron/blob/7b5c89c437d27fec... Value of SecurityIdentity.getPrincipal() can be seen when trace log is enabled due to https://github.com/wildfly-security/wildfly-elytron/blob/7b5c89c437d27fec... Since it seems there is currently no documentation related to this topic I cannot say whether it is real bug. [~dlofthouse] could you please provide some clarification?
