[keycloak-user] Tooltip IdP mapper "Username Template Importer" as example "${ALIAS}.${CLAIM.sub}" but it does not work

Hi, When configuring an "Username Template Importer" as a mapper of an identity provider, the tooltip says that it could be "${ALIAS}.${CLAIM.sub}" but "sub" is not an accessible claim. AbstractClaimMapper.getClaimValue() only looks into token.getOtherClaims(), so only claims binded by @JsonAnySetter are accessible, not sub iss jti... I patch it : Map<String, Object> jsonObject = token.getOtherClaims(); jsonObject.put("jti", token.getId()); jsonObject.put("sub", token.getSubject()); jsonObject.put("iss", token.getIssuer()); jsonObject.put("azp", token.getIssuedFor()); Because I need to be able to get these attributes. Either the tooltip or the code has a bug ?
