Examine the LDAP configuration file(s). #grep bindpw: /etc/security/ldap/ldap.cfg If the returned entry has an unencrypted password (not like “bindpwd:{DES}”) , this is a finding. If the LDAP configuration file contains an encrypted password accessible by regular users on the system, this is a finding. #ls –l /etc/security/ldap/ldap.cfg Check for unencrypted SSL keyfile password. #grep ‘^ldapsslkeypwd’ /etc/security/ldap/ldap.cfg If the returned entry has an unencrypted password (not like “ldapsslkeypwd:{DES}”) , this is a finding.

Fix Text (F-33177r1_fix)
Remove any passwords from LDAP configuration files. The bindpw (bind password) can be encrypted with the mksecldap command. #mksecldap Stash the SSL key database file with the gsk7cmd or ikeyman commands. #gsk7cmd < or > ikeyman Comment out the ldapsslpwd line to use stashed password. The password stash file must reside in the same directory as the SSL key database, and must have the same name as the key database, but with an extension of .sth instead of .kdb.
