> Faster LDAP group name resolution with ActiveDirectory
> ------------------------------------------------------

> Key: HADOOP-12782
> URL: https://issues.apache.org/jira/browse/HADOOP-12782

> The typical LDAP group name resolution works well under typical scenarios. However, we have seen cases where a user is mapped to many groups (in an extreme case, a user is mapped to more than 100 groups). The way it's being implemented now makes this case super slow resolving groups from ActiveDirectory.
> The current LDAP group resolution implementation sends two queries to a ActiveDirectory server. The first query returns a user object, which contains DN (distinguished name). The second query looks for groups where the user DN is a member. If a user is mapped to many groups, the second query returns all group objects associated with the user, and is thus very slow.
> After studying a user object in ActiveDirectory, I found a user object actually contains a "memberOf" field, which is the DN of all group objects where the user belongs to. Assuming that an organization has no recursive group relation (that is, a user A is a member of group G1, and group G1 is a member of group G2), we can use this properties to avoid the second query, which can potentially run very slow.
> I propose that we add a configuration to only enable this feature for users who want to reduce group resolution time and who does not have recursive groups, so that existing behavior will not be broken.
