Years ago I came across this handy chart that showed a small history of eDirectory versions and platform support. Recently I decided to update it to include the newer versions and more details about the versions of operating systems supported.
Note: This information has not been vetted by Novell, but I did collect it from the various documentation available.
If you have any additional rows and columns you'd like to see leave a note, or if you have corrections, by all means please let me know!!
Many thanks to whomever the original author was for starting this handy tool!
I've updated this image based on your feedback to include SLES 11 and the 64 bit version of eDirectory. Many thanks also to all the folks on the TTP list that helped fill this in!!
Disclaimer: As with everything else at Cool Solutions, this content is definitely not supported by Novell (so don't even think of calling Support if you try something and it blows up).
It was contributed by a community member and is published "as is." It seems to have worked for at least one person, and might work for you. But please be sure to test, test, test before you do anything drastic with it.
