Someone was asking about directory services before. Just wanted to let people
know that Novell has just released eDirectory 8.7 and is offering a special
promotion right now. Basically you can, "Download 250,000 user licenses of
Novell eDirectory to begin building a scalable identity management
infrastructure for your organization. In addition to the free user licenses of
Novell eDirectory, Novell will also include 25,000 user licenses of the Novell
DirXML LDAP Driver to enable you to synchronize your existing directory with
Novell eDirectory."

So their pretty much giving away their directory.

They have a version of eDirectory for Linux, AIX, Solaris, WinNT/2K and of
course Netware.
