Discussion

If cached authentication information is out-of-date, the validity of the authentication information may be questionable.

Check Content

If LDAP authentication is not required, this is Not Applicable.

Verify the "/etc/security/ldap/ldap.cfg" file to see if the following two keywords have a value that is greater than "900" seconds:

# grep -i usercachetimeout /etc/security/ldap/ldap.cfg
usercachetimeout: 900

# grep -i groupcachetimeout /etc/security/ldap/ldap.cfg
groupcachetimeout: 900

If any of the above keywords does not exist, is commented out, or any value of the above keywords are greater than "900", this is a finding.

Fix Text

Edit the "/etc/security/ldap/ldap.cfg" file to set the following two keywords to have value of "900":
usercachetimeout
groupcachetimeout

Restart LDAP client using command:
# /usr/sbin/restart-secldapclntd
