Good day, dear colleagues!
Please advise a good engine for the forum that would be able to log into AD and to use a domain account "scarabi" or by not very strong napiling, work with domain groups.
Of functionality, in addition to AD have the ability to quickly add files the message editor to quickly add messages, create closed sections, the ability to subscribe to topics and changes of topics using email, rss.
Have administration experience Simple Machines Forum, its capabilities are more than satisfied, but how to make friends with the AD I found.
Preferably something opensource, but can be considered commercial products.
