38.4. Adding a new IdM ID range
In some cases, you may want to create a new IdM ID range in addition to the original one; for example, when a replica has run out of IDs and the original IdM ID range is depleted.
Adding a new IdM ID range does not create new DNA ID ranges automatically. You must assign new DNA ID ranges to replicas manually as needed. For more information about how to do this, see assigning DNA ID ranges manually.
Procedure
To create a new IdM ID range, use the
ipa idrange-addcommand. You must specify the new range name, the first ID number of the range, the range size, and the first RID number of the primary and secondary RID range:# ipa idrange-add IDM.EXAMPLE.COM_new_range --base-id 5000 --range-size 1000 --rid-base 300000 --secondary-rid-base 1300000 ipa: WARNING: Service dirsrv@IDM-EXAMPLE-COM.service requires restart on IPA server <all IPA servers> to apply configuration changes. ------------------------------------------ Added ID range "IDM.EXAMPLE.COM_new_range" ------------------------------------------ Range name: IDM.EXAMPLE.COM_new_range First Posix ID of the range: 5000 Number of IDs in the range: 1000 First RID of the corresponding RID range: 300000 First RID of the secondary RID range: 1300000 Range type: local domain rangeRestart the Directory Server service on all IdM servers in the deployment:
# systemctl restart dirsrv@IDM-EXAMPLE-COM.serviceThis ensures that when you create users with UIDs from the new range, they have security identifiers (SIDs) assigned.
Optional: Update the ID range immediately:
Clear the System Security Services Daemon (SSSD) cache:
# sss_cache -ERestart the SSSD daemon:
# systemctl restart sssd참고If you do not clear the SSSD cache and restart the service, SSSD only detects the new ID range when it updates the domain list and other configuration data stored on the IdM server.
Verification
You can check if the new range is set correctly by using the
ipa idrange-findcommand:# ipa idrange-find ---------------- 2 ranges matched ---------------- Range name: IDM.EXAMPLE.COM_id_range First Posix ID of the range: 882200000 Number of IDs in the range: 200000 Range type: local domain range Range name: IDM.EXAMPLE.COM_new_range First Posix ID of the range: 5000 Number of IDs in the range: 1000 First RID of the corresponding RID range: 300000 First RID of the secondary RID range: 1300000 Range type: local domain range ---------------------------- Number of entries returned 2 ----------------------------
