GEN001374 - The /etc/nsswitch.conf file must not have an extended ACL.

Information

The nsswitch.conf file (or equivalent) configures the source of a variety of system security information including account, group, and host lookups. Malicious changes could prevent the system from functioning or compromise system security.
NOTE: AIX does not use the /etc/nsswitch.conf file. This check is not applicable.

Solution

Remove the extended ACL from the /etc/nsswitch.conf file.
# acledit /etc/nsswitch.conf
