Eric Schoen created SOLR-18141:
----------------------------------
Summary: Improve MultiAuthPlugin with Kerberos
Key: SOLR-18141
URL: https://issues.apache.org/jira/browse/SOLR-18141
Project: Solr
Issue Type: Bug
Components: Authentication
Affects Versions: 9.8.1
Environment: Debian Bookworm
Reporter: Eric Schoen
I need to develop client side support for Kerberos authentication outside of a
Windows environment, so it would be helpful to retain Basic Auth while also
supporting Kerberos. But it looks like MultiAuthPlugin doesn't handle
KerberosPlugin's constructor parameters. I don't see any explanation of
solr.KerberosPlugin or org.apache.solr.security.hadoop.KerberosPlugin's
constructor parameters. Is it possible to create an entry for Kerberos auth in
the multiauth plugin spec?
