The authentication of automated LDAP connections between systems must not use passwords since more secure methods are available, such as PKI and Kerberos. Additionally, the storage of unencrypted passwords on the system is not permitted.
Verify LDAP is running on the system. To check to see if the system is an LDAP server run: # ps -ef | grep ldap Find out which LDAP is used (if not determined via the command above). # rpm -qa | grep ldap If using nssldap: # grep base /etc/ldap.conf Check to see if the base is set to something besides the default of "dc=example,dc=com". If using openldap: # grep suffix /etc/openldap/slapd.conf Check whether the system is an LDAP client: # grep server /etc/ldap.conf # grep server /etc/openldap/ldap.conf Check whether the server option has an address other than the loopback, then check the nsswitch.conf file: # grep ldap /etc/nsswitch.conf Look for the following three lines: passwd: files ldap shadow: files ldap group: files ldap If all three files are not configured to look for an LDAP source, then the system is not using LDAP for authentication. If the system is not using LDAP for authentication, this is not applicable. Check for the "bindpw" option being used in the "/etc/ldap.conf" file. # grep bindpw /etc/ldap.conf If an uncommented "bindpw" option is returned, then a clear text password is in the file, and this is a finding.
Edit the "/etc/ldap.conf" file to use anonymous binding by removing the "bindpw" option.
Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
text/turtle or
Accept: application/rdf+xml.
