[keycloak-dev] Identity Provider Claim to Role Mapper new features

Mon Sep 16 05:32:43 EDT 2019

Hi,

Thanks for the feedback. I’ve attached a screenshot of how I thought it could look like. If the two features go into the new mapper there would be another checkbox for the regex values. Another argument for a new mapper for the multiple claims is that the existing data model is not designed to support multiple claims. Basically there is a config Map<String, String> where all the configuration of a mappers goes into. To configure a claim the map uses

“claim” -> “name_of_the_claim”
“claim.value” -> “value_of_the_claim”

To not break existing functionality and have multiple claims configured in the config map the logic around this would get at least a little bit redundant. For the multiple claims to role mapper I thought of entries like the following in this map

“claims.name_of_the_claim1” -> “value_of_the_claim1”
“claims.name_of_the_claim2” -> “value_of_the_claim2”

Mit freundlichen Grüßen / Best regards

Thanks,

The regexp option on the current mapper makes sense to me. There is a bit of lacking of testing around mappers today though, so we would need to make sure current test if it exists is extended, or one is created.

For multiple claims I think it may be better to have a new mapper for it, but not 100% sure. On one side the current mapper starts getting to many options/configurations, but on the other hand the multiple claims mapper may turn out to be just a copy of the current one with the addition on supporting multiple claims. Do you have any idea how it would be configured/look like?

Hi,

sure, I have the following scenarios in mind:

1.)    Regex: If a user logs in with the identity provider the organization of the user with a specific hierarchal pattern is sent, e. g. "organization": "INST_CSS_BSV_OS2". If a user is in an organization that starts with "INST_CSS" he should get the role "inst_css_user". With a regular expression as claim value you could map the claim "organization" with regex "INST_CSS.*" to the role "inst_css_user". Without regular expressions you need to specify every organization individually.

2.)    Multiple Claims: If a user logs in with the identity provider the organization and a country for a user is sent. If a user comes from the "United States" and is in a "CSS" organization I would like to assign the role "css_us_user". This would be possible if multiple claims are supported in the claim to role mapper.

Could you provide some use-cases/examples please?

Hi,

I would like to contribute features to the Identity Provider Claim to Role Mapper.

1.)    Regex support for claim values: My suggestion for this feature is to introduce a new checkbox in the Claim to Role Mapper to turn regex support for claim value on or off. By default the regex box is unchecked, so currently existing mappers won't change.

2.)    Support for multiple claims: Instead of providing one claim and one claim value the idea is to provide a map of claim -> claim value. The role will be assigned when all provided claims match the token. Is it okay to change the existing Claim to Role Mapper for this feature or should I rather introduce a new mapper for this, e. g. Multiple Claim to Role Mapper?

What are your thought on that? Do these two features have a chance to be contributed?

Best regards
