If you are upgrading from a version of LISTSERV prior to 15.5: Due to non-backward-compatible changes to the format of LISTSERV's SIGNUP files, and the addition of non-reversible subscriber password encryption, L-Soft
STRONGLY RECOMMENDS that, prior to upgrading, a full backup be made of your LISTSERV installation.
LISTSERV 16.0 for Unix is built with LDAP support. This support is an integral part of LISTSERV and it cannot be disabled. Because of this, an appropriate LDAP implementation is required and must be installed on your machine. In some cases (particularly under Linux) the version of LDAP on our development machines may differ from that on your production or test machine.
If LDAP is already installed on your machine but you get errors indicating that LISTSERV cannot find the LDAP libraries, it should be possible to relink 'lsv' to realign the library pointers. In practice this will happen only when the precompiled 'lsv' is used; for sites that require DBMS functionality, the realignment will happen transparently. For information on LISTSERV/LDAP integration, please see the
LISTSERV-LDAP Documentation, which is available separately.
Sites running LISTSERV 14.4 or later may use the LAK input tool in the Web Administration interface to apply and check their new LAK before upgrading.
The installation kits found on L-Soft's web site can be used either to install a new copy of LISTSERV or to upgrade an existing installation. To download LISTSERV 16.0, simply go to L-Soft's Web site and download an evaluation copy of LISTSERV or LISTSERV Lite, then follow the installation instructions for your operating system.
