--- Comment #17 from Louis Lenders xerox_xerox2000@yahoo.co.uk 2009-10-11 16:21:57 --- In current git the behaviour of LsaLookupSids seems to be OK. The problem is now in LsaLookupNames2 as stated in my lsat comment: The problem now seems to be LsaLookupNames2 doesn't handle a single domain name correctly ("NT AUTHORITY" is passed in, and LsaLookupNames2 returns ERROR_NONE_MAPPED)
