OCPBUGS-56908: sanitize IdP names used in group sync annotations#252agawai wants to merge 1 commit into
Conversation
Kubernetes annotation keys cannot contain spaces. Identity provider names like "AIF - Keycloak" are otherwise legal, but writing oauth.openshift.io/idp.<raw name> on Group objects fails API validation and blocks login when OpenID groups claims are enabled. Sanitize the IdP name used in the annotation key so group sync succeeds without changing the OAuth CR name. Signed-off-by: Akanksha Gawai <280726545+agawai@users.noreply.github.com>

WalkthroughThe group mapper now sanitizes identity-provider names before creating Kubernetes synchronization annotation keys. Group lifecycle operations and tests use the sanitized keys, including validation for invalid characters, empty names, and length limits. ChangesIdP annotation sanitization

Use a collision-resistant identity-provider annotation key.
idpAnnotationKey replaces invalid characters with - and truncates the result to 59 bytes. Thus A B and A-B, or names differing after byte 59, produce the same key. removeUserFromGroup then treats one IdP's sync marker as another's and can remove membership that the other IdP still requires. Encode the original name injectively or append a stable digest.
