Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Petr Vobornik 2014-09-09 15:16:51 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/4527

We need to know the number of the users to set appropriately big ID ranges.

If there are more users on the AD than the size of the range, they will be unable to log in.

We currently do some detection of the number of the users, but it works only for the users that have POSIX attributes defined in the AD. This does not have to be the case, and also, the users need not to be defined in the root domain (see #4525).

We should leverage the fact that SIDs are issues sequentially and try to estimate the number of the users on the AD side in a effective manner.

This RFE was postponed upstream, it will not be done in FreeIPA 4.2. This Bugzilla will be therefore postponed also.
Comment 6 Dmitri Pal 2019-03-13 20:45:00 UTC 
Hello,

While it is a valid RFE and would be quite useful there is not pressing demand on it.
The issue will be tracked upstream and once addressed there will brought back into the distribution.

Thank you,
Dmitri
