It should be possible using the core MediaWiki software for bureaucrats to be able to reset passwords for users. Either Special:ResetPass could be modified or a new Special: page could be created. It might also be a good idea to log such resets.
On Wikimedia wikis, this would have to be delegated to Stewards, due to the dangerous privilege escalation potential it would provide if given to Wikimedia-style bureaucrats.
