Subject [jira] [Commented] (HADOOP-8121) Active Directory Group Mapping Service
Date Tue, 13 Mar 2012 17:30:40 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8121?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13228529#comment-13228529
] 

Allen Wittenauer commented on HADOOP-8121:
------------------------------------------

It isn't unrealistic for super large enterprises to have tens of thousands of group definitions
(one previous employer had just shy of 10k!).  Is it possible for someone to be in so many
groups as to hit the search limit? Well, it depends upon how the LDAP server is configured.
 If we don't want to fix this, then it should at least be mentioned in the docs that search
limits are not supported and/or will result in unpredictable behavior.
