As with a lot of 90s software, it’s a bit more complicated than which source code did they download (or, rather, mail order on floppy… because it was the 90s). Not the least of which is due to the fact that many of the projects don’t exist anymore and there weren’t that many copies to begin with.
However, they both embrace and extend LDAP and Kerberos among other open and not open projects of the time. Both choices were related to the results of the Protocol Wars and Microsoft’s attempts, in the 90s, to do to the Internet what Google is doing today.
