Bryan Bende updated NIFI-2003:
------------------------------
Resolution: Fixed
Status: Resolved (was: Patch Available)
> User Identity Normalization
> ---------------------------
>
> Key: NIFI-2003
> URL: https://issues.apache.org/jira/browse/NIFI-2003
> Project: Apache NiFi
> Issue Type: Sub-task
> Components: Core Framework
> Reporter: Matt Gilman
> Assignee: Bryan Bende
> Fix For: 1.0.0

>
> NiFi allows for a number of different authentication mechanisms. Once the
> user has authenticated he/she is identified by their identity. This is a
> String that is returned by the authentication mechanism. For certificate or
> LDAP based authentication this is a DN. For Kerberos it is the user
> principal. If the same user authenticates through different mechanisms, they
> may have different identities. In 0.x this was annoying but not a big deal as
> it was just a matter of (re)assigning the user role. However, in 1.x this is
> unacceptable given the nature of fine grain authorization and the number of
> access policies that must be duplicated.
>
> Because we’ve delegated user authorization and the underlying implementation
> can choose to authenticate however they want, we cannot rely on our internal
> User/Group/Policy model to enforce any normalization.
>
> After discussions with Andy, Joe, and Bryan, I think we have a proposal that
> will provide the flexibility needed without requiring continued maintenance
> by an Administrator. Additionally, it shouldn’t require too many additional
> development cycles.
>
> The basic idea is to add configurable mappings that will run after the user
> identity determined but before any authorizations. These mappings are
> purposefully decoupled from the authentication mechanisms to reduce
> duplicative configurations and support a more flexible solution. These
> mappings could be configured in nifi.properties as follows. Here, the last
> segment of the property name is an identifier used to associate the pattern
> with the replacement value.
