> UserPrincipal lookup in the JAAS' BackingEngine
> -----------------------------------------------
>
> Key: KARAF-4496
> URL: https://issues.apache.org/jira/browse/KARAF-4496
> Project: Karaf
> Issue Type: Improvement
> Reporter: Yurii Rashkovskii
> Assignee: Jean-Baptiste Onofré
> Priority: Minor
> Labels: jaas
> Fix For: 4.1.0
>
>
> I have a suggestion for improving org.apache.karaf.jaas.modules.BackingEngine
> Currently, the only way to lookup an individual user (as far as I can tell)
> is to iterate through the result of BackingEngine#listUsers() and find the
> required user. This is fine if the number of users is reasonably low.
> However, when JAAS infrastructure is used for public systems (say, a SaaS),
> it quickly becomes a bottleneck.
> I suggest adding something like `public UserPrincipal lookupUser(String
> name)` to avoid this problem (also, it should return `null` if no such user
> found , or throw an exception)
> I am happy to contribute a PR promptly if this change will be approved.
> Thoughts?
