Internally IPA framework attempts to resolve ID override anchors. We can
actually optimize this code as ipaOriginalUID attribute contains
normalized name already, written their when the override is created and
never changed afterwards. This should speed up the resolution of large
Martin, can you file a ticket for that? The code in question is
baseidoverride.convert_anchor_to_human_readable_form() which could
benefit from passing in entry_attrs and checking ipaoriginaluid there.
If 'ipaoriginaluid' is missing, do analysis of ipaanchoruuid like it is
As an alternative I wonder if the WebUI can be made asynchronous in the
sense that it displays the raw data (the SID in this case) first and run
the lookups in the background and replace the SID when the name is
available. I've seen some Windows tools behaving this when looking up
large numbers of SIDs.
We have that for external group members already.
However, in the ID overrides there is no SID as it is. The RDN of the ID
override is 'ipaAnchorUUID' attribute which is an encoding of a target
reference. We don't need to resolve it because we already have it
resolved in 'ipaOriginalUid' attribute -- this was done to help Schema
Compatibility and SASL mapping plugins which cannot resolve
ipaAnchorUUID value. We just need to make its use consistent across the
