Subject [jira] [Commented] (HADOOP-8121) Active Directory Group Mapping Service
Date Tue, 13 Mar 2012 16:36:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8121?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13228502#comment-13228502
] 

Jonathan Natkins commented on HADOOP-8121:
------------------------------------------

a) I'm a little unclear under what circumstances you expect this to hit a search limit. Would
you expect that users would belong to more groups than the search limit can support in a single
search? That seems surprising to me. Like I said earlier, if the plug-in is misconfigured,
and you have a search filter that is not sensible, say (objectClass=*), yes, you would probably
hit a search limit. In that case, an exception would be through in getGroups, and logged,
alerting an admin to the fact that there's a problem.

b) You're right, I'll document this somewhere.

Regarding documentation, where is the most appropriate place for it to go?
