Triple-DES can result in CVE-2016-2183 and CVE-2016-6329 which
are known as the SWEET32 Birthday attack.
CORRECTION FOR APAR 'SE65732' :
-------------------------------
Triple-DES will be removed from the LDAP default supported
cipher list.

the applications. If Triple-DES is required temporarily, it can
be enabled using LDAP WebAdmin, iNavigator and ldapmodify to
change either the attribute ibm-slapdSslCipherSpec or the
attribute ibm-slapdSslCipherSpecs of the entry 'cn=SSL,
cn=Configuration' to the correct values.
