Subject [jira] [Updated] (HADOOP-12751) While using kerberos Hadoop incorrectly assumes names with '@' to be non-simple
Date Sat, 30 Jan 2016 09:17:39 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-12751?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bolke de Bruin updated HADOOP-12751:
------------------------------------
    Attachment: 0004-HADOOP-12751-leave-user-validation-to-os.patch

- whitespace fix

- Tests have been adjusted to check "fall through" of the rules. Invalid names do not really
exist anymore .

Caveat: does hadoop allow for "/" (slash) in user names? If not patch needs to be adjusted.

> In the scenario of a trust between two directories, eg. FreeIPA (ipa.local) and Active
Directory (ad.local) users can be made available on the OS level by something like sssd. The
trusted users will be of the form 'user@ad.local' while other users are will not contain the
domain. Executing 'id -Gn user@ad.local' will successfully return the groups the user belongs
to if configured correctly. 
> However, it is assumed by Hadoop that users of the format with '@' cannot be correct.
This code is in KerberosName.java and seems to be a validator if the 'auth_to_local' rules
are applied correctly.
> In my opinion this should be removed or changed to a different kind of check or maybe
logged as a warning while still proceeding, as the current behavior limits integration possibilities
with other standard tools.
> Workaround are difficult to apply (by having a rewrite by system tools to for example
user_ad_local) due to down stream consequences.
