--------------------------------------
Summary: Ambari rebuilds custom auth_to_local rules changing its
case sensitiveness option (/L) depending on the case_insensitive_username_rules.
Key: AMBARI-21418
URL: https://issues.apache.org/jira/browse/AMBARI-21418
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.5.0
Reporter: Tomas Sokorai
Ambari changes the auth to local custom rules /L state on rebuild depending on
case_insensitive_username_rules.
How to reproduce:
1) Kerberize Ambari.
2) Make sure these kerberos settings are set as follows:
case_insensitive_username_rules = false
manage_auth_to_local = true
3) Add custom auth_to_local rule:
{code:java}
RULE:[1:$1@$0](.*@HDP01.LOCAL)s/.*/ambari-qa//L
{code}
(NB: HDP01.LOCAL realm was chosen to avoid matching the default kerberos realm,
EXAMPLE.COM in my tests)
4) Add a new service to the cluster that has kerberos configuration, in my
case, tested with adding Spark2.
5) After successful service addition, check the auth_to_local mappings again;
the mapping we added in point 3 should now be missing the /L and be:
{code:java}
RULE:[1:$1@$0](.*@HDP01.LOCAL)s/.*/ambari-qa/
{code}
