Why are the changes needed?
When LDAP Authentication is used ST Token is created and saved in the cache, but it is never freed up.
This is causing continuous increase in heap usage, eventually causing out-of-memory for kyuubi server pods.
This changes is added to clear ST Tokens. Also ST Group is added to avoid any race condition during clean up.
How was this patch tested?
This patch was tested in our customer environment. We observed there's no more continuous heap increase after the fix.
Was this patch authored or co-authored using generative AI tooling?
Cursor auto-complete feature was used.
