Comments:
In announce letter 915-238, all license part numbers were withdrawn from marketing effective March 10, 2016 for Dxxxxxx and April 12, 2016 for Exxxxxx. The V6.4 media is still available for electronic download only.
IBM will only offer 1 year of extended support beyond the EOS date. [...]
As a courtesy to our Connections customers we would like to raise awareness to this date in case a migration to another supported LDAP server needs to be planned.
We offer support for a variety of LDAP servers and recommend OpenLDAP as an alternative:
