Flush the identity mapping cache

You can flush the ID map cache to remove in-memory copies of all or specific identity mappings.

About this task

Modifications to ID mappings may cause the cache to become out of sync and users might experience slowness or stalls when authenticating. You can flush the cache to synchronize the mappings.

This procedure is available only through the command-line interface.


  1. Open a secure shell (SSH) connection to any node in the cluster and log in.
  2. Run the isi auth mapping flush command.
    The following command flushes all identity mappings on the cluster:
    isi auth mapping flush --all
