#3498 ipa-adtrust-install crashes with multiple local ranges
Closed: Fixed None Opened 9 years ago by mkosek.

There can be multiple ranges set if the first one was depleted or for example there are users migrated from previous IdM solution. We should support that.

# ipa idrange-find
----------------
2 ranges matched
----------------
  Range name: IDM.LAB.BOS.REDHAT.COM_id_range
  First Posix ID of the range: 694000000
  Number of IDs in the range: 200000
  Range type: local domain range

  Range name: local_range
  First Posix ID of the range: 1200000
  Number of IDs in the range: 200000
  First RID of the corresponding RID range: 1000
  First RID of the secondary RID range: 1000000
  Range type: local domain range

This program will setup components needed to establish trust to AD domains for

WARNING: 2 existing users or groups do not have a SID identifier assigned.
Installer can run a task to have ipa-sidgen Directory Server plugin generate
the SID identifier for all these users. Please note, the in case of a high
number of users and groups, the operation might lead to high replication
traffic and performance degradation. Refer to ipa-adtrust-install(1) man page
for details.

Too many ID ranges

Sumit's suggestions for ipa-adtrust-install RID generation:

If there are multiple ranges there are different ways to set the RID-ranges. E.g. you can pick the idrange with the lowest POSIX ID and assign the lowest RID range to it. Then take the one with the next lowest and so on. Alternatively the lowest RID range is assigned to the oldest idrange, and so on.

maybe the logic can be like: lookup idranges, check if RID bases must be added, return if not, check if RID ranges must be added for more than one range, fail if yes, check if the given RID bases are not in conflict with existing ones, fail if yes, add RID ranges.

with this we fail only if RID bases must be added for more than one range, which can be fixed separately.

Rename "trusts" component to "Trusts" to achieve correct sorting.
