* Hi gtema,

Reverted the marker approach as you suggested.

https://review.opendev.org/c/openstack/keystone/+/999379

The actual fix: `sizelimit` in `_paged_search_s` was abandoning the LDAP cursor mid-page, poisoning the connection pool — subsequent requests returned 0 non-deterministically.

Fix is `sizelimit=0` always, truncation handled in Python by `@driver_hints.truncated`. Marker pagination documented as unsupported.
