> Faster LDAP group name resolution with ActiveDirectory

> 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.
