Hi,

The Monitoring, Backup and Automation agents can use two OS environment variables to set specific Kerberos parameters:

• KRB5CCNAME : the file used for the kerberos cache
• KRB5_CONFIG : the Kerberos library configuration file

This is something that should be documented in:

• https://docs.opsmanager.mongodb.com/current/reference/monitoring-agent/#mongodb-kerberos-settings
• https://docs.opsmanager.mongodb.com/current/reference/backup-agent/#mongodb-kerberos-settings
• https://docs.opsmanager.mongodb.com/current/reference/automation-agent/#mongodb-kerberos-settings
• https://docs.cloudmanager.mongodb.com/reference/monitoring-agent/#mongodb-kerberos-settings
• https://docs.cloudmanager.mongodb.com/reference/backup-agent/#mongodb-kerberos-settings
• https://docs.cloudmanager.mongodb.com/reference/automation-agent/#mongodb-kerberos-settings

Please note that the KRB5CCNAME should be set to different files (one per Agent process) if there are multiple agents running on the same server. If you are running for example a Monitoring Agent and a Backup Agent on a server, they should use different kerberos cache files by using different KRB5CCNAME values.
