AcceptSecurityContext error, data 532

Crazy print domain authentication failed in my Elasticsearch logs today

{"type": "server", "timestamp": "2022-04-18T08:55:38,254Z", "level": "WARN", "component": "o.e.x.s.a.AuthenticationService", "": "Elasticsearch", "": "Elasticsearch-data-0", "message": "Authentication to realm my_ad failed - authenticate failed (Caused by LDAPException(resultCode=49 (invalid credentials), diagnosticMessage='80090308: LdapErr: DSID-0C090447, comment: AcceptSecurityContext error, data 532, v3839\u0000', ldapSDKVersion=4.0.8, revision=28812))", "cluster.uuid": "_wzs-T4YQ3Kow34VH5RYbA", "": "Rqtii0AnT8eP0JcyP-6AVQ" }

Is this someone logging into Elasticsearch constantly, or is there a problem with the authentication between Elasticsearch and the ad domain

Looks like the lattter to me.
