Description Dmitri Pal 2012-06-07 09:52:22 EDT

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/1366

One of the biggest performance issues with RFC2307bis servers is that, because a member attribute provides only a DN, we have to perform a lookup for that DN to determine if it is a user or a group.

One way we could optimize this and save ourselves some lookups would be to compare the DN to the set of configured search bases if (and only if) the user and group search bases do not overlap.

This check should be done once at startup time and saved in the ldap_id_ctx. It should only be done if the ldap_user_search_base and ldap_group_search_base are both populated during initialization (in other words, if we are autodetecting the search base from the RootDSE, don't bother doing this comparison then).

Comment 3 Martin Kosek 2014-06-17 08:23:23 EDT

Will be fixed as a part of bigger refactoring in SSSD (rebase bug 1109756).

Comment 5 Kaushik Banerjee 2015-01-16 05:34:36 EST

SanityOnly verification with sssd-1.12.2-42.el7

All ldap backend automation tests pass.
