I saw your question regarding the changes in Keycloak version 24.0.3 around redirect URIs. The documentation does seem confusing, but here are a few key points:
Exact Matching: The guide mentions that redirect URIs need an exact string match when they contain a userinfo part or "access a parent directory" (e.g., /../).
Wildcard Usage: This suggests wildcards might still be usable in other cases, such as when the URI doesn't contain a userinfo part or access a parent directory.
Documentation: The terminology around "accessing a parent directory" is confusing, as we don't typically think of URL paths in this way. This makes the change feel more opaque. Given the ambiguity, I share your confusion. Reaching out to the maintainers or testing thoroughly in your environment might be necessary.
I hope this helps somewhat.
