Ok. And Apache projects can not use GPLed products for the same reasons. (And 
according to FSF GPLed projects can't use Apache licensed products, due to 
some patent grant issues...)

Great. I don't think anyone here is questioning the honorable intents of 
Sleepycat. This is purely a principle of Open/Free idealogies, of which one 
or the other is not "more right", just different and not legally compatible.

That may be true for the majority of users, up until the point where the 
project is no longer maintained. However, ASF believes it is not up to us to 
decide what the downstream users want to do with the software.

AFAICT, Apache DS needs to lift the Sleepycat usage out of the Apache 
Directory Server, and re-surface the Berkley DB backend externally.
The immediate problem is to put in a suitable replacement.


P.S. Mental Note to Incubation members; This slipped through Incubation, so I 
think we need to tighten the checks over there. Each project listing all 
external dependencies and which license they are all in, in a table, perhaps.
