Description
Some authentication implementations can be configured to use cached authenticators. If cached authentication information is out-of-date, the validity of the authentication information may be questionable. The organization-defined time period should be established for each device depending on the nature of the device; for example, a device with just a few administrators in a facility with spotty network connectivity may merit a longer caching time period than a device with many administrators.

Check Text ( C-50389r769201_chk )
Use "security login show -authentication-method domain" to see users configured to authenticate with Active Directory. If ONTAP cannot prohibit the use of cached authenticators, this is a finding.

Fix Text (F-50343r769202_fix)
Configure ONTAP to make use of Active Directory to authenticate users to prohibit the use of cached authenticators with "security login create -user-or-group-name -authentication-method domain -application ssh".
