Check Text (C-215205r958828_chk)

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.
