Description
The alarm module checks the status of the Kerberos resource in Manager every 80 seconds. This alarm is generated when the alarm module detects that the Kerberos resources are abnormal for six consecutive times.
This alarm is cleared when the Kerberos resource recovers and the alarm handling is complete.

Impact on the System
The component WebUI authentication services are unavailable and cannot provide security authentication functions for web upper-layer services. Users may be unable to log in to FusionInsight Manager and the WebUIs of components.
Possible Causes
The OLdap resource on which the Okerberos depends is abnormal.
Procedure
Check whether the OLdap resource on which the Okerberos depends is abnormal in the Manager.
- Log in the Manager node in the cluster as user omm.
Log in to FusionInsight Manager using the floating IP address, and run the sh ${BIGDATA_HOME}/om-server/om/sbin/status-oms.sh command to check the information about the current Manager two-node cluster.
- Run the sh ${BIGDATA_HOME}/om-server/OMS/workspace0/ha/module/hacom/script/status_ha.sh command to check whether the OLdap resource status managed by HA is normal. (In single-node mode, the OLdap resource is in the Active_normal state; in the two-node mode, the OLdap resource is in the Active_normal state on the active node and in the Standby_normal state on the standby node.)
- See the procedure in ALM-12004 OLdap Resource Abnormal to resolve the problem. After the OLdap resource status recovers, check whether the OKerberos resource status is normal.
- If yes, the operation is complete.
- If no, go to 4.
Collect fault information.
