RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Nathan Kinder 2012-07-23 21:03:05 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/412

It was reported by the IPA team that operation related to memberof was slow.

This will simply require running the memberOf tests to check for regressions for verification.

    Trac Ticket #412 - memberof performance enhancement
    
    https://fedorahosted.org/389/ticket/412
    
    Fix description:
    memberof.c: replaced DN strings with Slapi_DN and set the
    normalized info to Slapi_Value flags.  It reduces the number
    of slaip_dn_normalize_ext call by ~25%.
    
    attr.c, slapi-plugin.h: introduced a new API slapi_attr_
    value_cmp_ext which takes Slapi_Value instead of struct
    berval.  By replacing with Slapi_Value, the value flag
    (e.g., normalized info) can be passed to the syntax plugin.
    
    value.c: changed slapi_value_compare to call slapi_attr_
    value_cmp_ext instead of slapi_attr_value_cmp.
    (cherry picked from commit 6a21e8e9be90de76549b8fb37dc744ca48234e00)

Comment 3 Jenny Severance 2012-07-24 12:20:05 UTC

QE verify sanity only, no regressions found with memberOf testing.

Comment 5 Sankar Ramalingam 2012-11-15 20:18:53 UTC

This needs to verified by running mbo and memOfEnhancement acceptance tests and check no regressions.

Comment 6 Sankar Ramalingam 2012-11-19 10:45:11 UTC

No regressions found for member of tests. Hence marking the bug as Verified.
MemberOf run elapse time : 00:50:15
    MemberOf run Tests PASS      : 100% (75/75)
