Symptoms

aaa.log:

./aaa.2023-08-23.0.log.gz:org.springframework.security.oauth2.jwt.JwtException: An error occurred while attempting to decode the Jwt: Signed JWT rejected: Another algorithm expected, or no matching keys found

 

Cause

Fejlen i aaa.log:

2023-08-24T07:39:26.964Z ERROR [] [https-jsse-nio-9090-exec-1] [][][][TRACE_ID:97d2704ca1652f50][] [c.e.b.a.s.s.DefaultSsoService.lambda$1(71)] - SSO login issue: {}
org.springframework.security.oauth2.jwt.JwtException: An error occurred while attempting to decode the Jwt: Signed JWT rejected: Another algorithm expected, or no matching keys found

Det betyder, at AAA forventer HS256, som er standard, men OKTA returnerer altid en RS256-signatur.

 

Resolution

  • Log på PowerProtect Data Manager ssh
  • cd /usr/local/brs/lib/aaa/config
  • vim application-sso.properties
  • Kontroller, om variablen aaa.sso.client.alg = RS256, hvis ikke, skift derefter fra HS256 til RS256.
  • Afslut fra vim (:wq!)
  • AAA-genstart
