[keycloak-dev] Dynamically compute LIST values in ProviderConfigProperty

[Marek Posolda]

UserFederationMapper is using ConfiguredProvider like other mappers. In 
Role LDAP Mapper, I want to display combobox with the list of all the 
realm clients, so user can choose, which client roles will be mapped to 
LDAP roles. I need RealmModel instance for this. Currently I can see 
those possible solutions:

1) Make admin requests to have RealmModel (and possibly ClientModel) 
available in KeycloakContext (currently is null). As I mentioned in 
other mail yesterday, we can possibly set RealmModel in 
RealmsAdminResource.getRealmAdmin . Similarly ClientModel can be set 
later before ClientResource is instantiated.

2) Add RealmModel as argument on 
"ConfiguredProvider.getConfigProperties" method

3) Use method "getConfigProperties(RealmModel realm)" just in my 
provider and ignore the "getConfigProperties()" from ConfiguredProvider.

Currently I have it already working with (3), but I don't like it very 
much... It seems to me that (1) is best. Solution (2) is also not very 
good IMO (also because protocolMappers are tight to the client and not 
to the realm)

It looks to me that IdentityProviderMapper may also need realm to 
retrieve the roles dynamically. The current solution where user manually 
needs to fill "clientName.roleName" is likely not very good (not user 
friendly and it won't work for realm role with dot in the name like 
"my.cool.realm.role" ).

Also I wonder if ProviderConfigProperty should support MAP type in 
addition to the list? Then we can use key/value pairs instead of just 
flat values. That will allow that users will see client/role names in 
the combobox in the UI, but chosen value will be client/role ID.

WDYT?
